What are the forces of the golf swing?
Defining the Forces of the Golf Swing. Your feet generate forces when they push against the ground. These forces act to propel your body and create motion. 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 ...
How many newtons does a golf ball use?
If a player exerts an applied force of 1000 Newtons of force to the golf ball, the golf ball will apply and equal reaction force of 1000 Newtons onto the golf putter, causing the ball to start rolling.
How much force does a golf club exert on a ball?
The golf club only comes into contact with the ball for approximately 1/200 of a second. The face of the club is grooved so that during contact with the ball it can grip the ball and create backspin which enables aerodynamic lift. While searching for a measurement of the force of a golf club on a golf ball I found four different measurements.
How is Newton’s law applied to golf?
This law can be applied to golf to a golf putt for example. If a player exerts an applied force of 1000 Newtons of force to the golf ball, the golf ball will apply and equal reaction force of 1000 Newtons onto the golf putter, causing the ball to start rolling.

How many G does a golf ball experience?
In fact, during certain stages of impact, the ball experiences more than 50,000-g's of acceleration! An oversized driver can increase distance up to 2% for a 1″ OFF CENTER hit when compared to that of a normal-sized driver. The benefit of having an oversized driver is only for OFF CENTER hits.
What is torque in a golf swing?
Torque, which equates to Force x Distance, is the turning force that changes an object's rate of rotation. In a golfing context, this usually refers to the rotation of the shoulders during the backswing, and the hips during the swing itself.
How do you calculate golf ball force?
Newton's Second Law of Motion is proven through the way the golf ball flies through the air. Newton's law states that the net force of an object (Fnet) is equivalent to the object's mass (m) multiplied by the object's acceleration (a). In other words, Fnet = ma.
How much energy is in a golf swing?
At impact most swings were associated with less than 1 J of strain energy in the shaft and no swings were estimated to have more than 2 J in the shaft at impact. The maximum amount of strain energy, calculated at any point in the swing, from the participants in this study was found to be approximately 6 J.
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 type of motion is a golf swing?
angular motionThe dynamics of the golf swing is important to every golfer's game. To hit a golf ball, the golfer swings a club while standing at the side of a motionless ball positioned on the ground. Such a swing involves angular motion. In physics, angular motion is defined as the movement of a body about a fixed point, or axis.

Do lighter golf balls go further?
Because the ball is not slowed down as much if it is heavier, it will travel farther than a lighter ball. A heavier ball will have an unfair advantage to that golfer.
How do Newton's laws apply to golf?
The impact between a club and the ball produces equal and opposite forces, demonstrating Newton's Third Law of Motion, and also transfers momentum from the club to the ball. "Science of Golf" is produced in partnership with the United States Golf Association and Chevron.
How does each force act independently on the moving golf ball?
For a greater distance to be achieved, one needs to increase the acceleration of the ball by increasing the force with which the ball is struck or swinging the club faster. The golf club only comes into contact with the ball for approximately 1/200 of a second.
How much mass does a golf ball have?
The United States Golf Association regulates the mass of golf balls to keep it at a constant 45.9 g (1.62 oz.). Once the ball is in flight, several forces act upon it. Some of these forces include: gravity, aerodynamic drag, and aerodynamic lift. Each force acts independently on the moving golf ball. For a greater distance to be achieved, one needs ...
How long does a golf club stay in contact with the ball?
The golf club only comes into contact with the ball for approximately 1/200 of a second. The face of the club is grooved so that during contact with the ball it can grip the ball and create backspin which enables aerodynamic lift.
What causes a golf club to project off the head?
The force of the club head on the ball causes the ball to compress and apply an equal amount of force on the club. The impact of this equal and opposite force has little effect on the continuation of the swing. This initial force of the club causes the ball to project off the club head. The United States Golf Association regulates the mass ...
What governs the game of golf?
While most players would like to believe that it is their natural talent that enables them to be great golfers, the laws of physics are what govern the game of golf. From the moment the golf ball is at rest on the tee to the the time it spends rolling along the putting green, the movements of the ball can be predicted and calculated due to ...
What is the leading factor in the distance the ball travels?
The force of the club hitting the ball is the leading factor in the distance the ball travels. The distance the ball travels is directly related to the force that is applied from the head of the golf club, the angle at which the force is applied, gravity, as well as air and wind resistance.
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.
How is acceleration related to force?
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. Every action has an equal and opposite reaction.
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.
Where is the release point in golf swing?
Part of the physics of a golf swing (from the point of view of the golfer), means finding the release (wrist uncocking) point so that at the bottom position, where the players hands are directly above the ball, the golf club is in the vertical position parallel to his arms.
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.
Is golf physics complicated?
The Physics Of A Golf Swing. The physics of a golf swing is deceptively more complicated than one might imagine. At first glance it might appear as simple as swinging a club and hitting the ball. But in fact, there is quite a bit more to it. There is the importance of technique obviously, but there is also some interesting physics ...
How much force does a golf ball have to have to roll?
If a player exerts an applied force of 1000 Newtons of force to the golf ball, the golf ball will apply and equal reaction force of 1000 Newtons onto the golf putter, causing the ball to start rolling.
What are unbalanced forces in golf?
In this case during a real game of golf, the unbalanced forces are the force of gravity and force of air (air resistance). Also, this law can be applied to the golf ball sitting on the golf tee. Hypothetically, the golf ball would stay on the tee forever until acted upon by an unbalanced force, in this case the force applied by the golf club.
How to find net force?
Newtons second law states that the net force is equal to the mass times the acceleration (Fnet=ma). When given the mass and acceleration, the Fnet can be found easily by multiplying the two. When given 2 of the 3 variables, the unknown variable can be found by rearranging the equation, or by using kinematic equations for finding the acceleration.
How are normal forces applied in a swing?
Normal forces are applied by the feet downward or perpendicular to the ground. Weight is transferred to the back foot during the backswing and to the front foot during the downswing.
What are the forces in golf?
These forces act to propel your body and create motion. 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.
Why is the linear component of the golf swing important?
This action defines the linear component of the movement. The linear movement of the body during the golf swing is very important because it is from this movement that the body develops momentum that enhances the rotational speed and power of the hips.
How does weight transfer in a downswing?
Weight is transferred to the back foot during the backswing and to the front foot during the downswing. When weight is shifted to one foot, the amount of force supplied by the foot increases while the normal force applied by the other foot decreases. This action defines the linear component of the movement.
What is the effect of a golf swing on the foundation of a house?
When faults occur in lower body mechanics, the effect on the golf swing is analogous to cracks in the foundation of a house. When a stable base is lost, swing efficiency erodes. The most common fault in lower body mechanics is sliding.
How is shear applied in a swing?
Shear force is applied by the feet along the surface of , or parallel to, the ground. Through the swing, shear forces are being applied by both feet. These shear forces create torque that turns the hips around the axis of the trunk. This defines the rotational component of the lower body movement. The rotational component can be related most ...
What degree is the peak of a golf club?
Lateral force – Peak occurs between top-of-swing and lead arm at 45 degrees. Vertical torque – Peak occurs between lead arm being 45 degrees and the lead arm being parallel to the ground. Vertical force – Peak occurs between lead arm being parallel to the ground the club shaft being parallel to the ground.
How much pressure can you create at one time?
Pressure can only be expressed in relation to the mass or weight of the body. Therefore, if you weigh 150 pounds, you can only create 150 pounds of pressure at one time. However, when we direct that mass at a larger object than our mass, all of a sudden that larger mass directs an opposite and equal reactionary force.
When we shift the center of mass, we create a pressure shift?
When we shift (translate and/or torque) the center of mass, we create a pressure shift as the body has to “rebalance” the mass or body. This pressure shift can help us understand some aspects of the golf swing, but when it comes to producing power, force and torque are where it’s at. Pressure can only be expressed in relation to ...
Can ground reaction forces be measured?
While it may seem obvious, it’s important to remember ground reaction forces are in visible and can only be measured using force plates. With that said, their tends to be apprehension about discussing how we use the ground as most people do not have access to 3D dual force plates.
