How momentum and impulse is used in golf?
Impulse changes the momentum of an object. It increases the speed of a golf ball when the time of contact between the golf ball and club is increased. The longer the contact time between the golf ball and the club, then the greater the velocity of the golf ball and the further it will travel.

In kilograms. Times by velocity which is in meters per second.
Can a baseball have the same momentum as a bowling ball?
Yes. Since momentum is the product of mass and velocity, a large velocity for the baseball can produce a momentum equal to that of a slower-moving bowling ball.
What is the advantage of an airbag in reducing injuries during collisions?
Air bags are used in motor vehicles because they are able to reduce the effect of the force experienced by a person during an accident. Air bags extend the time required to stop the momentum of the driver and passenger. During a collision, the motion of the driver and passenger carries them towards the windshield.

Get yourself in that same feel and see if you can feel that pulling force.
Why is momentum important in golf?
Golf is really about the movement of an object through space with a guided collision into the golf ball. Being able to understand the movement of momentum in the right manner is essential in increasing distance, control and also in helping your body stay injury free.
Why momentum is considered equal to zero when a body comes to rest?
The momentum of any object that is at rest is 0. Objects at rest do not have momentum - they do not have any "mass in motion." Both variables - mass and velocity - are important in comparing the momentum of two objects.
How is momentum conservation 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.
Which is necessary condition for the total momentum of a system to be conserved?
The law of conservation of momentum says that the momentum of a closed system is constant in time (conserved). A closed (or isolated) system is defined to be one for which the mass remains constant, and the net external force is zero. The total momentum of a system is conserved only when the system is closed.
At what speed airbag opens?
Frontal air bags are generally designed to deploy in "moderate to severe" frontal or near-frontal crashes, which are defined as crashes that are equivalent to hitting a solid, fixed barrier at 8 to 14 mph or higher. (This would be equivalent to striking a parked car of similar size at about 16 to 28 mph or higher.)
Can airbags break your ribs?
Airbags deploy so quickly that the impact can result in broken bones. Not only can it fracture your wrist and fingers, but also fracture your rib cage, skull, or facial bones.
Can airbags break your neck?
Broken bones and internal injuries. Frontal airbags are positioned directly in front of your ribcage. Therefore, if the impact force of the bag punches you in the chest, chin, or abdomen, it can easily cause ribs to compress, neck vertebrae, and damage to internal organs.
What forces act on a golf ball?
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 to increase the acceleration of the ball by increasing the force with which the ball is struck or swinging the club faster.
How does Newton's second law apply to golf?

The forceMoreThis means the motion of an object with balanced or zero net forces will remain constant. The force of Earth's gravity pulling down on a ball is balanced by the upward push of the tee.
What is the effect of an impulse on an object?
The impulse acting on an object produces a change in momentum of the object that is equal in both magnitude and direction to the impulse.
What changes the direction of the ball's momentum vector?
The direction of the ball's momentum vector was changed by an external force (the wall).
How does momentum change in a two body system?
The total momentum of the two-body system remains constant. An object exerts an impulse on a second object changing the momentum of the second object. The reaction of the second object provides an impulse on the first object changing its momentum. Overall, since the action and reaction forces are equal and opposite and the time each force acts is the same for both, the change in momentum of the second will be equal and opposite to the change in momentum of the first leaving the total momentum of the system unchanged.
What is the velocity of a bullet with a mass of m1 = 3.4 kg?
28. A rifle with a mass of m1 = 3.4 kg fires a bullet with a mass of 8.1 g (0.0081 kg). The bullet moves with a velocity of 860 m/s after the rifle is fired. If external forces acting on the rifle can be ignored, what is the magnitude of the recoil velocity of the rifle?
What is the product of the average force times the time the force acts?
Impulse is the product of the average force times the time the force acts.
What is momentum in math?
Momentum is a vector pointing in the direction of the velocity, so a change in direction implies a change in momentum.
Which direction do defensive backs move after a collision?
Since the momentum of the defensive back player is higher, the players will move in his direction (south) after the collision.
