What happens to momentum when a moving ball hits another ball?
Watch a moving cue ball hit a resting pool ball. At impact, the cue ball stops, but transfers all of its momentum to the other ball, resulting in the hit ball rolling with the initial speed of the cue ball. In an inelastic collision, the total momentum of the system is conserved, but the total kinetic energy of the system is not conserved.
When does momentum happen in football?
According to the broadcasters, momentum happens more often near halftime (there are more mentions in the second and third quarter than in the first and fourth), and it tends to cluster (once it's mentioned, it's likely to be discussed again within a few plays).
How do you calculate the momentum of a golf ball?
Let's calculate the momentum of the golf ball in the above example. If the golf ball has a mass of .05 kg, and a velocity of 15 m/s, then what is its momentum? (Answer: momentum= .05 kg*15 m/s= 0.75 kg m/s)
How does force affect the speed of a golf ball?
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: The impulse (the force times how much time the force is applied) will cause the golf ball to speed up or slow down.
How does momentum affect golf?
The ball gains momentum because the club pushes on it, and the club loses momentum because the ball pushes back.

How is momentum applied in ball games?
At impact, the cue ball stops, but transfers all of its momentum and kinetic energy to the other ball, resulting in the hit ball rolling with the initial speed of the cue ball. In an inelastic collision, momentum is conserved, but the total kinetic energy of the system is not conserved.
Is momentum conserved when hitting a golf ball?
The total system momentum is the same before the collision as it is after the collision. Total system momentum is clearly conserved.
How is the resulting change in momentum affected?
If the force is constant while the time of impact is doubled, the impulse is doubled and the resulting change in momentum is doubled.
Why do balls lose momentum when dropped?
All of the balls lost momentum because there are no perfectly elastic collisions in the real world. Even the most elastic collisions are slightly inelastic. When a ball bounces, energy is transferred to heat, noise or internal energy, which decreases the amount of momentum.
How is momentum conserved when a ball is dropped?
Short answer is: The Earth itself accelerates (ever so slightly) toward the object at the same time. The opposite-direction velocity of the Earth will be exactly proportional to the ratio of the object's mass to Earth's mass, thus exactly balancing ("conserving") momentum.
What is momentum affected by?
The amount of momentum that an object has is dependent upon two variables: how much stuff is moving and how fast the stuff is moving. Momentum depends upon the variables mass and velocity. In terms of an equation, the momentum of an object is equal to the mass of the object times the velocity of the object.
How is momentum used in sports?
Momentum is a commonly used term in sports. When a sports announcer says that a team has the momentum they mean that the team is really on the move and is going to be hard to stop. An object with momentum is going to be hard to stop.
What happens to lost momentum?
That is, the momentum lost by object 1 is equal to the momentum gained by object 2. In most collisions between two objects, one object slows down and loses momentum while the other object speeds up and gains momentum. If object 1 loses 75 units of momentum, then object 2 gains 75 units of momentum.
How is sports momentum conserved?
Conservation of Momentum Momentum is always conserved in a closed system, but most sporting situations in the real world are not a closed system. For example, when a baseball bat hits the ball, the ball will be squished to a certain degree. After few milliseconds, it rebounds back.
What is the second law in football?
With regard to football, the second law shows how much force is expended when one player blocks or tackles another player. Although weight is usually used when referring to how much a person like a football player weighs, the player's mass is more important when applied to the second law. Mass is a measure of how much matter (total number of atoms) ...
What is Newton's first law of motion?
Newton stated within his first law of motion that any object of mass at rest (velocity, designated as v, is zero) will tend to stay at rest, and any object in motion (velocity is not zero) will tend to stay in motion at the same speed and direction (acceleration, designated as a, is zero), unless acted upon by a force.
What are the types of collisions in football?
Tackles (acts of forcing opponents to the ground) and blocks (acts of preventing opponents from interfering with movements toward the goal) are types of collisions in football. The forces that two or more football players exert on one another due to their mass and momentum can be described by the three laws of motion developed by English physicist ...
What is the second law of acceleration?
In other words, the second law can be stated: F net = ma. Acceleration refers to how rapidly an object is changing its speed with respect to time. Force is the action that speeds mass up (acceleration) or slows it down (deceleration).
What does the minus sign mean in a collision?
The minus sign shows that the forces are in opposite directions. Since both players exert the same force on each other during the collision and continue to do so over the same time interval, but in opposite directions, then one player gains exactly the same momentum (mass × velocity) that the other player loses.
What is the law of inertia?
The first law is often called the law of inertia because the term inertia means the resistance to motion.
Is football governed by classical physics?
Even though it does not appear that tackles and blocks are orderly on the football field, each and every one of them is strictly governed by the fundamental laws of classical physics—compliments of Newton's three laws of motion. see also Football (American); Football injuries. World of Sports Science.
What is momentum in sports?
In the engineering and physics world, momentum refers to the quality of motion that an object has, and it depends on the mass and velocity of the object:
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 to calculate momentum?
After this lesson, students should be able to: 1 Calculate the momentum of a moving object. 2 Recognize that momentum is proportional to mass and velocity. 3 Explain that in a closed system, momentum is conserved in both elastic and inelastic collisions. 4 Describe how collisions and momentum play an important role in the design of safe automobiles.
What is the law of conservation of momentum?
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.".
Why do engineers consider momentum when designing vehicles?
In a head-on collision, the front end of a car is designed to crumple, making the collision inelastic. It takes energy to crumple the front of the car and this is what absorbs some of the impact.
Why do engineers use crumple zones?
A crumple zone is designed into motor vehicles to absorb the main impact of the energy being transferred during a crash, so the people inside don't get hurt.
What happens when a golf ball hits a ping pong ball?
When the golf ball strikes the floor, it bounces up and collides with the ping-pong ball. This action transfers the greater momentum of the golf ball to the ping-pong ball, which responds by rising faster and higher.
Homework Statement
Place a golf ball on top of a basketball, and drop the pair from rest so they fall to the ground.The golf ball stays on top of the basketball until the basketball hits the floor. The mass of the golf ball is 0.0459 kg, and the mass of the basketball is 0.587 kg.
The Attempt at a Solution
In these equations since momentum is conserved I thought that all of the momentum would just be emitted to the golf ball in the end, with the momentum of the basketball (initial) added to the momentum of the golf ball (initial) giving a total momentum of 2.832 kg*m/s, but that was not the case.
Answers and Replies
With conservation of momentum alone, you have only one equation and two unknowns. So you are not going to arrive at a unique solution for v1 and v2: there are infinitely many. In other words, after the collision, conservation of momentum only demands that the total momentum be the same as before.
What happens if your center of mass is right up next to the ball?
If your center of mass is right up next to the ball, you will not have room to get your mass in motion and stay in motion all the way through impact, while also allowing you to have full extension of your arms with the feeling of a full release in your golf swing. This is the first fundamental concept you will lean when taking ...
How to do a squat in golf?
Step 1: Without a club, pick out a target and start walking towards it, while in stride turn 180 degrees right with your back facing the target and continue moving towards it, then turn back to the left with the front of your body once again facing the target.
What happens if you turn left before dropping your shoulders?
Drop the shoulders and arms (If you start turning left before the shoulders have dropped, they will start pulling you out of balance and there will be an involuntary pull that will not let you continue moving towards your target smoothly and will most often cause a shot that starts left and the continues to draw farther off that line).
How to walk without a golf club?
Without a club, pick out a target and start walking towards it, while in stride turn 180 degrees right with your back facing the target and continue moving towards it, then turn back to the left with the front of your body once again facing the target. You should be able to stay walking on a straight line, even though you are turning back and forth. It may help to put a tee in the ground and walk towards it so that you get an idea of how straight your line is.
Is it good to practice walking through a shot?
As you get more sensitive , you can lessen the amount of room you need to be falling through your shots. It is really good to practice walking through these as well and practicing off uphill slopes. It will give you a lot of feedback as to how well the sequencing and timing was feeding together.
Can you hook a ball if you don't get far enough forward?
The funny thing is, as long as your body is moving forwards, there is not ever a problem with a hook. Because even if you don’t get far enough forwards with your mass at impact, but it is still moving in that direction, the ball starts a little left and go straight.
What type of collisions have greater momentum?
For example, a heavier object going the same speed as a lighter object would have greater momentum. Sometimes when moving 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.
Why is learning how the human body interacts with the ball during impact important?
Learning how the human body and equipment interacts with the ball during impact or how the human body interacts with the inside of a car during a crash, helps engineers design better sports equipment and safer vehicles.
What is sports engineering?
Sports engineering is becoming a popular specialty field of study. Some engineers dedicate their research to understanding collisions between balls and bats; others study the effects of a golf ball colliding with the head of a golf club. Mechanical engineers consider momentum and collisions when designing vehicles.
What is the force exerted by the first object on the second object?
For any pair of interacting objects, the force exerted by the first object on the second object is equal in strength to the force that the second object exerts on the first, but in the opposite direction (Newton's third law). (Grades 6 - 8) More Details
What is the energy of an inelastic collision?
In an inelastic collision, the total momentum of the system is conserved, but the total kinetic energy of the system is not conserved. Instead, the kinetic energy is transferred to another kind of energy such as heat or internal energy. A dropped ball of clay demonstrates an extremely inelastic collision.
What happens after the clubface meets the ball?
But after the clubface meets the ball, the position of your club and your feet and your torso have nothing to do with whether it ends up on the green or in the sand trap.
What forces carry you past the point of impact?
Allow simple physics to take control: Momentum and inertia will carry your swing past the point of impact, and centrifugal force will complete the trajectory between the two end points. It’s the same strategy athletes use in any sport that involves striking one object with another.
