There are many forces involved in hitting a quality golf shot, however, the basic forces acting upon the golf ball relate directly back to Newton’s 3 laws of motion. First Law: An object in motion will stay in motion while an object at rest will remain until acted upon by an outside force. This relates to “Why doesn’t your ball fall off the tee?”
How does newton's second law apply to golf?
Newton's second law: The acceleration of an object produced by a net applied force is directly related to the magnitude of the force, the same direction as the force, and inversely related to the mass of the object. In golf this applies when the force of the club hits the ball propelling it in a direction. Newton's third law:
What are the unknown quantities in the golf swing equation?
The other unknown quantities in the equation such as r, m, lG, IG are constants based on the properties of the golf club and the parameters of the golfer's swing. Using trial and error, one must input different wrist uncocking (release) angles, in the above equation (for θo ), until α = 180° at θ = 180° (in the solution).
What happens to a golf ball in a collision?
In a collision, the amount of time the golf ball is in contact with the club and/or the amount of force applied will cause the object to speed up or slow down. The impulse (the force times how much time the force is applied) will cause the golf ball to speed up or slow down.
What happens to the Golf Club at the bottom of the swing?
But in the bottom part of the swing, the golf club begins to "release" and the angle between it and his arms begins to rapidly increase (since his wrists are now uncocked), and the club moves radially outwards as a result. At the bottom of the swing the golf club is almost perfectly parallel to his arms.

How many Newtons are in a golf swing?
"The normal force rises to approximately 2,000 lbs. (9 kN) during the half-millisecond of impact."
What forces are involved in golf?
Two types of forces are important to the golf swing: normal forces and shear forces. Normal forces are illustrated in the linear components of the swing, and shear forces are illustrated in the rotational components of the swing. Normal forces are applied by the feet downward or perpendicular to the ground.
What forces act on the golf tee when it is falling in the bottle?
When the hoop is pulled, gravity causes the golf tee to fall inside the bottle.
How does Newton's 3rd law apply to golf?
Newton's 3rd law states with every reaction, there is an equal and opposite reaction. As the golf club comes down at the bottom of the swing, the club head comes in contact with the golf ball at a certain force, as they come in contact, the force of the club on the ball is equal to the force of the ball on the club.
How is golf an example of Newton's second law?
Second Law: Force equals mass times acceleration (f=ma). When a golf club carries an unbalanced force it carries a change in velocity. The change in velocity is acceleration. The greater the force applied to the golf ball the greater the acceleration.

What is the physics application in golf?
The physics of golf is a detailed subject. It involves forces and aerodynamics, occurring during the hitting of the ball, during its flight through the air, during the run of the ball (after landing), and during the putt. Golfers often put much effort into perfecting their golf game.
What does Newton's 1st law of motion state?
Newton's first law states that if a body is at rest or moving at a constant speed in a straight line, it will remain at rest or keep moving in a straight line at constant speed unless it is acted upon by a force.
How much mass does a golf ball have?
1.620 ozUnder the rules of golf, a golf ball has a mass no more than 1.620 oz (45.9 g), has a diameter not less than 1.680 inches (42.7 mm), and performs within specified velocity, distance, and symmetry limits.
What are Newton's laws in golf?
Newton's first law: An object in motion tends to stay in motion and an object at rest tends to stay at rest unless it's acted on by an outside force. An example is this is a ball flying though the air. As the ball encounters air resistance and gravity it slows down.
How do you know if a golf club hits the ball?
In golf this can be seen by the club hitting the ball. As the club hits the ball it's the action. When the ball flies away it's the reaction to that.
What is Newton's first law of motion?
Newton's first law of motion is related to inertia, it states that: an object in motion will remain in motion and an object at rest will remain at rest unless acted upon by an unbalanced force.
How is inertia shown in the picture?
Inertia is shown in the picture as the ball is currently in motion, and will remain in motion until it is acted upon when it reaches the cup; creating a balanced force.
How many people can play golf?
Golf can be played in groups consisting of any number of people (generally 1-4). In golf the player (s) try hit a golf ball with their golf clubs into the hole to beat their own previous score, or play competitively against other teams. Scoring is different from other sports, as the objective is to play through the course in as least strokes as possible (a score of 65 beats a score of 70). Each course typically consists of 18 holes (or some other multiple of 9), and has a variety of holes ranging from par 3 to par 5. Par is how many strokes it takes to break even, or score 0 for that hole. Each hole has a tee box, where the player starts the hole; from there, the fairway (an area of semi-short grass) leads up to the green, which contains the hole and has is extremely short grass to allow for putting; however an area known as the rough surrounds all parts of the course, the taller grass in them makes it harder to hit the ball further than on the fairway. Courses also include obstacles including sand traps (pits of sand), water hazards (a body of water), and areas that are out of play (you can't hit the ball there). When playing through a hole, the player has a variety of clubs to choose from, each of which is used in a variety of situations.
What are the forces that are constantly acting on the golf ball?
The forces are constantly acting on the golf ball. These forces are friction and gravity. Friction is a result of the ball rolling against the grass on the green. Gravity pulls the ball downward.
What is the second law of the ball?
The second law says that every object when acted upon by force will move with an acceleration dependent on the mass of the object. ( F=am) is the reason why when the club face hits the ball, some go farther than others.
What happens to the golf club at the bottom of the swing?
At the bottom of the swing the golf club is almost perfectly parallel to his arms.
Why do golf clubs uncock?
Uncocking the wrists allows the golf club to "straighten out", and in the process gain additional speed which translates into a harder hit than if the golf club were held rigid (meaning the wrists are not allowed to rotate during the swing).
What is the correct angle to uncock your wrists?
However, looking at the strobe picture of Bobby Jones' swing one might (mistakenly) conclude that the correct swing angle to uncock your wrists is at approximately 120°, simply because that is when the increase in club angle α becomes very noticeable. Thus, analyzing the physics of a golf swing using a dynamics approach, will yield more accurate information than if someone were to just observe a golfer's swing, and draw conclusions from that. The lesson here is that certain information can only come to the surface when the physics of the problem is examined carefully.
How to release wrists in golf?
And prior to this release point he just has to keep his wrists cocked; meaning, maintain his grip in a fixed position so that the club maintains a constant angle with his arms. Once he releases his wrists the physics takes care of the rest, and the club will move radially outwards due to the effect of centripetal acceleration.
Why is the first point important in golf?
The importance of the first point is fairly obvious. You must generate good swing speed to hit the ball hard enough, so that it goes far . The second point is not as obvious. To understand the physics of a golf swing one must consider the mechanics of rotational motion.
What are the two things that go into making a golf shot?
There are two main components that go into golf swing physics. Both these will result in the best possible shot: 1. Good swinging speed of the arms and shoulders. 2.
Where does the swing energy come from?
So where does the swing energy come from? It comes from the muscles in the torso and shoulders which swiftly rotate the golfer's arms and club through the swing. Uncocking the wrists at the optimal swing angle means that, as much energy as possible is transferred to the club head (in the form of kinetic energy), just before it contacts the ball.
Why does a golf ball react with a golf club?
A reaction between a golf ball and golf club proves this to be true because they apply same amount of force back onto each other, but in the opposite direction. For example, the golf ball applies same momentum back on the club, but travels in the same direction as the club due to the smaller mass. For example, if the club applies a force ...
What happens when a golf club hits a golf ball?
During the impact between a golf club and a golf ball, the force of the golf club affects the ball. This collision causes the ball to travel into the air. In a collision, the amount of time the golf ball is in contact with the club and/or the amount of force applied will cause the object to speed up or slow down. Newton's Third Law:
What is the third law of golf?
Newton's third law states that every action has a equal and opposite reaction.
How does physical conditioning help golfers?
Physical conditioning will help to recruit the muscles in the correct sequence and to optimum effect. To maximise the accuracy of chipping and putting shots, the golfer should produce a lower grip on the club and a slower/shorter backswing.
How does biomechanics help golfers?
Golf biomechanics applies the principles and technique of mechanics to the structure and function of the golfer in an effort to improve golf technique and performance. A common recommendation for technical correction is maintaining a single fixed centre hub of rotation with a two-lever one-hinge moment arm to impart force on the ball. The primary and secondary spinal angles are important for conservation of angular momentum using the kinetic link principle to generate high club-head velocity. When the golfer wants to maximise the distance of their drives, relatively large ground reaction forces (GRF) need to be produced. However, during the backswing, a greater proportion of the GRF will be observed on the back foot, with transfer of the GRF on to the front foot during the downswing/acceleration phase. Rapidly stretching hip, trunk and upper limb muscles during the backswing, maximising the X-factor early in the downswing, and uncocking the wrists when the lead arm is about 30 degrees below the horizontal will take advantage of the summation of force principle. This will help generate large angular velocity of the club head, and ultimately ball displacement. Physical conditioning will help to recruit the muscles in the correct sequence and to optimum effect. To maximise the accuracy of chipping and putting shots, the golfer should produce a lower grip on the club and a slower/shorter backswing. Consistent patterns of shoulder and wrist movements and temporal patterning result in successful chip shots. Qualitative and quantitative methods are used to biomechanically assess golf techniques. Two- and three-dimensional videography, force plate analysis and electromyography techniques have been employed. The common golf biomechanics principles necessary to understand golf technique are stability, Newton's laws of motion (inertia, acceleration, action reaction), lever arms, conservation of angular momentum, projectiles, the kinetic link principle and the stretch-shorten cycle. Biomechanics has a role in maximising the distance and accuracy of all golf shots (swing and putting) by providing both qualitative and quantitative evidence of body angles, joint forces and muscle activity patterns. The quantitative biomechanical data needs to be interpreted by the biomechanist and translated into coaching points for golf professionals and coaches. An understanding of correct technique will help the sports medicine practitioner provide sound technical advice and should help reduce the risk of golfing injury.
What is the role of biomechanics in golf?
Golf biomechanics applies the principles and technique of mechanics to the structure and function of the golfer in an effort to improve golf technique and performance.
Why are primary and secondary spinal angles important?
The primary and secondary spinal angles are important for conservation of angular momentum using the kinetic link principle to generate high club-head velocity. When the golfer wants to maximise the distance of their drives, relatively large ground reaction forces (GRF) need to be produced.
How did Newton's laws of motion help scientists?
By developing his three laws of motion, Newton revolutionized science. Newton’s laws together with Kepler’s Laws explained why planets move in elliptical orbits rather than in circles. Below is a short movie featuring Orville and Wilbur Wright and a discussion about how Newton’s Laws of Motion applied to the flight of their aircraft.
What is Newton's second law?
Newton’s second law talks about changes in momentum (m * V) so, at this point, we can’t separate out how much the mass changed and how much the velocity changed. We only know how much product (m * V) changed.
What did Isaac Newton do?
Sir Isaac Newton worked in many areas of mathematics and physics. He developed the theories of gravitation in 1666 when he was only 23 years old. In 1686, he presented his three laws of motion in the “Principia Mathematica Philosophiae Naturalis.”. By developing his three laws of motion, Newton revolutionized science.
What are some examples of aerodynamics?
Examples of action and reaction involving aerodynamics: 1 The motion of lift from an airfoil, the air is deflected downward by the airfoil’s action, and in reaction, the wing is pushed upward. 2 The motion of a spinning ball, the air is deflected to one side, and the ball reacts by moving in the opposite 3 The motion of a jet engine produces thrust and hot exhaust gases flow out the back of the engine, and a thrusting force is produced in the opposite direction.
What is the second law of force?
His second law defines a force to be equal to change in momentum (mass times velocity) per change in time. Momentum is defined to be the mass m of an object times its velocity V.
What is the tendency to resist changes in a state of motion?
This tendency to resist changes in a state of motion is inertia. There is no net force acting on an object (if all the external forces cancel each other out). Then the object will maintain a constant velocity. If that velocity is zero, then the object remains at rest. If an external force acts on an object, the velocity will change because ...

Why do pros hit the ball farther?
The pros hit the ball much farther because they are close to 50% faster than the average amateur golfer.
How much influence does loft have on launch angle?
If you want to launch the ball higher or lower, you have to change dynamic loft. This is the loft you present to the ball at impact, and has a 60-85% influence on the launch angle.
What is the difference between pros and amateurs on irons?
With irons, the pros hit the ball first, then the ground. Amateurs (well over 95%) strike the ground first. This factor relates strongly to distance control – a key source to a lower handicap.
How long does a golf ball stay connected?
The golf club strikes the ball, and they stay connected for approximately 3/4 of an inch.
Do you have to improve ground contact?
You don’t have to improve all of them – a simple adjustment to ground contact alone can have significant effects on your game and scores. However, the more of these factors you improve, the better and more optimized your golf game will be.
Can you play golf with a swing path?
You can play great golf with a swing path that is offline (as Bubba Watson regularly demonstrates). However, your swing path will determine whether you are a fader of the ball (curve the ball to the right onto your target), or a drawer of the ball (curve the ball to the left onto your target).
