What type of energy is released when hitting a golf ball?
During the downswing the potential energy is transferred to kinetic energy in the downward movement of the club (conservation of energy) before it hits the ball During the hit the ball is compressed against the club, and the shaft on the club simultaneously bends.
How do good golfers use science in their game?
Good golfers use the science of energy transfer. From high school, we learned that energy cannot be created; nor can it be destroyed. Energy can only be transferred from one state to another. When hitting a golf ball, energy from the body must be transferred to the ball.
What factors affect the distance a golf 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. The force of the club head on the ball causes the ball to compress and apply an equal amount of force on the club.
What energy systems do golfers use?
As golfers we utilise the ATP system when swinging the club and the aerobic system for the majority of the other time during the round. Basically, our sport is slow activity interspersed with a number of maximal efforts (swings) so it makes sense for golfer to train both the ATP and aerobic energy systems.
What causes the ball to curve when a pitcher throws a curveball quizlet?
When a pitcher wants to throw a curve ball, he spins the ball as he releases it. The rapid sideways spin of the ball causes the air on one side to move faster that the air on the other side. The difference in pressure causes the ball to move toward the side with lower pressure, curving in the direction of the spin.
What property of an object represents the ability of an object to resist distortion and to return to its original shape?
Unsourced material may be challenged and removed. In physics and materials science, elasticity is the ability of a body to resist a distorting influence and to return to its original size and shape when that influence or force is removed.
What is the relationship between the angular and linear velocity of a lever quizlet?
The equation, v = rω tells us that angular velocity and linear velocity are directly proportional as long as the radius of rotation is kept constant.
Why does one tend to shorten one's stride when walking on the ice?
Explanation: While walking on ice, one should take smaller steps because the smaller the steps are, the smaller, the backward and forward forces, which prevents you, to fall or slip.
Which property of an object resists a change in the state of rest or motion of the object?
InertiaInertia is the property of bodies to resist a change in their state of rest or motion.
What is the property of an object that resists change in its state of motion?
Inertia is the tendency of an object to resist changes in its state of motion.
What happens to the point linear velocity of an object as its angular velocity decreases?
It decreases because linear velocity is inversely proportional to angular velocity.
What is the relationship between angular motion and linear motion?
Angular motion is defined as, The motion of a body about a fixed point or fixed axis. It is equal to the angle passed over at the point or axis by a line drawn to the body....Relationship Between Linear And Angular Motion.FormulaLinearAngularMotion with time cancelled outv f 2 − v i 2 = 2 a sω f 2 − ω i 2 = 2 α Θ3 more rows
What is the equation for centripetal acceleration in terms of angular velocity and the radius?
a c = ω 2 r a_c = \omega ^2r ac=ω2r. a c a_c aca, start subscript, c, end subscript is radial acceleration, ω is angular speed, and r is radius of the circle. Radial acceleration is directly proportional to the product of the square of the angular speed and the radius of the curved pathway.
Why walking on ice one should take small steps to avoid slipping This is because smaller steps ensure?
Smaller steps give us a larger magnitude of the normal force, and the extra normal force leads to a large friction force. But the larger steps provide less normal force, and it will affect in small frictional force magnitude. So as soon as we walk on a slippery floor, we must take small steps to avoid slipping.
When walking on ice one should take small steps to avoid slipping This is because smaller steps ensure?
But the larger steps give less normal force, and it will cause small frictional force magnitude. So when we walk on a slippery floor, we should take small steps to avoid slipping. This is because smaller steps ensure the larger normal force. Therefore, option (C) is correct that is a larger normal force.
What are the forces that act upon execution of walking?
Forces Involved As the leg tries to move forward, the frictional force, in order to avoid the relative motion, acts in the forward direction on the foot. Assuming the ground is rough enough, the force manages to keep the foot in place. Since the foot does not move, the force is static friction and not dynamic friction.
Which of the following statements accurately represents the relationship between linear and angular motion?
Which of the following statements accurately represents the relationship between linear and angular motion? Angular motion of joints produces the linear motion of walking. Impulse is the product of force and time.
Which of the following terms is defined as the rate of change in velocity?
Acceleration is defined as the rate of change of velocity. Velocity is a vector, which means it contains a magnitude (a numerical value) and a direction. So the velocity can be changed either by changing the speed or by changing the direction of motion (or both).
Which of the following is defined as the body's ability to move a force a given distance?
Power. Which of the following is defined as the body's ability to move a force a given distance? Work. You just studied 35 terms! 1/35.
Where is moment of inertia found?
Moments of inertia can be found by summing or integrating over every 'piece of mass' that makes up an object, multiplied by the square of the distance of each 'piece of mass' to the axis. In integral form the moment of inertia is I=∫r2dm I = ∫ r 2 d m .
What energy system does a golf swing use?
It typically last around 1-2 seconds and the club can reach speeds of up to 240 kph. The golf swing is provided most of its energy from the ATP-PC system ( Energy Systems in Action, 2013).
What is the ATP-PC system?
The ATP-PC system, also known as the phosphagen system, uses molecules of phosphocreatine which is stored in muscles to create ATP. The phosphate in the phosphocreatine is used to make a molecule of ATP. This is done by adding the phosphate to ADP. This system cannot be sustained for long as there is only very little phosphocreatine in the muscle (Temertzoglou, 2014).
What are the three systems of golf?
The three systems are known by a variety of names but the most common ones are the adenosine triphosphate (ATP) system, anaerobic system (also known as the glycolytic system) and the aerobic system . I will explain these below and then we will talk about how they relate to your golf and training.
How does the ATP system work?
The ATP system uses the energy that is stored in the muscles themselves and, as this is a very low level, can only be used for a very short time with the energy obtainable being very limited. The energy available via this system would be completely exhausted between around six to ten seconds and takes a few minutes of rest to replenish itself. This system is used as a first energy source for things such as jumping up to answer the phone, run away from danger or to catch a falling child. This system kicks in immediately but, as mentioned before, the payoff is the small amount of energy that is able to be accessed by this system.
What are the three energy systems?
It is important to note that these energy systems are not used exclusively and most activities use a mixture of all three systems. The three systems are known by a variety of names but the most common ones are the adenosine triphosphate (ATP) system, anaerobic system (also known as the glycolytic system) and the aerobic system . I will explain these below and then we will talk about how they relate to your golf and training.
How to train ATP?
To train the ATP system you need to be using close to your maximal effort for short periods of time with adequate rest between exercises. Medicine ball throws, short sprints and golf specific exercises (i.e. golf swings) can all be used to train the ATP system. The effort phase needs to last between eight to fifteen seconds with enough rest between ...
Which energy system is used to keep you moving?
The second energy system available to the body to use is the anaerobic system and this system kicks in once the ATP system has used up its stores. This system will keep you moving for around an extra minute or so before it also runs out of fuel.
How to train your aerobic system?
A more formalised way to train your aerobic system is interval training .
How long does it take to concentrate on golf?
Golf also requires pretty steady concentration for 4 hours or more , there is considerable mental fatigue associated with that.
How many swings does a golf club make?
For sure! Swinging a golf club produces about 90% of peak muscle activity for each full swing. Depending on how well you play you may make as many as 40-50 full swings and 100 total swings in a round. That accumulates fatigue.
How to develop specific endurance in golf?
Further, by keeping track of and gradually increasing effort and number of swings in practice sessions, you can develop some very specific golf endurance.
What are the biomotor abilities for athletic performance?
To paraphrase Dr Tudor Bompa, strength, speed, endurance, co-ordination and mobility are the biomotor abilities for successful athletic performance. The dominant ability is the one from which the sport requires a higher contribution; for instance, endurance is the dominant ability in marathon running. "sports-specific program development should ...
What is endurance conditioning in golf?
I believe it is more beneficial, then, to redefine endurance/ conditioning for golf as the ability to make repeated efforts - a.k.a the ability to make the repeated swings you need to to play a round or to complete a practice session.
What does "maximal strength is the glass" mean?
Thirdly, as I once saw Mike Robertson put it (although I'm not sure who said it originally), "maximal strength is the glass, and everything else is liquid in the glass" - i.e. the more strength you have the more muscle endurance, power endurance, etc, you are able to have.
How does the body produce energy?
The body produces the energy required for neural (strength, power, speed) and metabolic (endurance) training by breaking down food and converting it into a usable form of fuel known as ATP. Because ATP has to be constantly replenished and re-used, the body uses three main systems of energy replenishment to facilitate ongoing training: ...
What is the force of a golf club on a golf ball?
However, one reference stated that the force of a golf club on a golf ball is 22.5 N. This reference consisted of review questions on topics that the author probably did not research. [Editor's note: The fourth entry in this table is definitely wrong. Force is the product of mass and acceleration, not mass and velocity as this source suggests. The irony is that this computation looks like it was a part of an answer key to some long vanished problem set. I hope this didn't foul up anyone's grade.]
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 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.
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 ...
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.
Which has more momentum, a rolling bowling ball or ping pong ball, going the same speed?
Which has more momentum, a rolling bowling ball or ping-pong ball, going the same speed? (Answer: Bowling ball, because it has more mass.)
How to explain a ping pong ball to a class?
Although they are about the same size, the golf ball is heavier. Explain that if you threw each ball the same speed, the golf ball would have greater momentum. This becomes painfully obvious with an example. Ask the students if they have ever played "dodge ball" or a similar game. Ask the students if they would rather play with the ping-pong ball or the golf ball. As students groan at the thought of getting hit with a golf ball, explain that the reason it would hurt more is because it would have substantially more momentum than a ping-pong ball. In this case, more momentum is due to the greater mass (weight) of the golf ball, and the momentum of the golf ball would translate into a big bruise on your leg!
How does momentum relate to collisions?
The amount of momentum an object has depends both on its mass and how fast it is going. For example, a heavier object going the same speed as a lighter object would have greater momentum. Sometimes, when objects collide into each other, momentum can be transferred from one object to another. There are two types of collisions that relate to momentum: elastic and inelastic. In a closed system, which means that there are no external forces acting on the objects that collide, both types of collisions follow the Law of Conservation of Momentum, which states "the total amount of momentum before a collision is equal to the total amount of momentum after a collision."
How high does a ping pong ball bounce?
Drop them both and watch as the ping-pong ball bounces as high as 10 feet. For a conservation of momentum demonstration, a ping-pong ball is held on top of a golf ball and they are dropped together.
What is potential energy?
A brief review of the concepts of potential and kinetic energy (covered in detail in the previous lesson) and momentum, is provided below: Potential energy is the energy that an object has because of its position. Potential energy can also be thought of as stored energy — energy that an object has, as an inherent characteristic, but is not in use.
What is the purpose of variables in math?
Use variables to represent quantities in a real-world or mathematical problem, and construct simple equations and inequalities to solve problems by reasoning about the quantities. (Grade 7) More Details
Does a golf ball bounce up?
And, since the golf ball transfers much of its momentum to the ping-pong ball, the golf ball hardly bounces up at all. This demonstration illustrates conservation of momentum, which states that momentum may be transferred from one object to another, but the total momentum must stay the same.
