When a ball is thrown up the magnitude of its momentum decreases and then increases.Does this violate the conservation of momentum principle?
No, this does not violate the conservation of momentum principle. As the ball is thrown up, its vertical velocity decreases, causing a decrease in momentum in that direction. However, the overall momentum of the ball (including horizontal and vertical components) remains constant in the absence of external forces. When the ball reaches its highest point and falls back down, its vertical velocity increases again, conserving the total momentum of the system.
Why does a ball rolled across a carpet eventually come to rest?
Friction between the carpet and the ball gradually slows down the ball's motion by converting its kinetic energy into heat. As the ball loses momentum, its speed decreases until it eventually stops moving.
What is the best example if transfer of momentum?
One of the best examples of transfer of momentum is when a cue ball strikes a stationary billiard ball, causing the stationary ball to move while the cue ball slows down or stops. This transfer of momentum demonstrates the principle of conservation of momentum in action.
Does a ball thrown upwards lose momentum?
Yes, a ball thrown upwards loses momentum as it moves against gravity. Gravity acts as a force that opposes the motion of the ball, slowing it down until it eventually reaches its highest point and then starts to descend back down.
What happens when a falling down ball hits the ground?
When a falling ball hits the ground, it experiences a sudden change in momentum and kinetic energy. The impact causes the ball to bounce back up due to the conservation of energy and momentum.

A ball rolls down a hill and hits a box the momentum of the ball decreases what happens to its momentum?
Momentum (as energy) isn't lost, it is transferred. Momentum is lost to friction when the ball is rolling, but in the described situation, the momentum is basically all transferred to the box upon impact. The box may tip over if light enough, or the box may break, or if heavy enough and built well enough, the box may absorb the impact and be left seemingly untouched. If the ball continues to roll after impact (if it bounces over/around/off of the box, then only partial momentum has been transferred to the box.

What happens to a ball rolling down a hill and hits a box and the momentum decreases?
The ball with mass (m) hits the box at a certain velocity (v) and the momentum (mv) is equal to the force (F) at impact times the time (t) it takes to stop resulting in a high acceleration that will deform the box. Mathematically, Ft = mv ; F = mv/t You would need to know the box stiffness property to determine the time
What does choking down on the golf club do?
Decreases the radius of the swing thus decreases the distance in which the ball will fly.
When a wrecking ball hits a wall it is not moving fast How can it have enough momentum to knock down a wall?
Momentum is a function of both mass and speed. The wrecking ball isn't moving very fast, but it is extremely heavy; that is where its momentum comes from.
Does a ball thrown upwards lose momentum?
Yes, a ball thrown upwards loses momentum as it moves against gravity. Gravity acts as a force that opposes the motion of the ball, slowing it down until it eventually reaches its highest point and then starts to descend back down.

What quality of a bowling ball enables it to plow through a set of pins without slowing down?
The bowling ball does slow down. Momentum is conserved. It's just that it's a heavy ball so it has a lot of momentum, and the pins are light so overall the ball doesn't slow down enough for us to notice.
As the speed of a rolling ball is increasing,the increasing speed is accompanied by?
momentum As the speed of a rolling ball is increasing, the increasing speed is accompanied by: a. increasing momentum.
Why did you use the height from the release point of the ball to the table top instead of all the way down to the floor?
We used height to make it gain momentum. The more the height, the more momentum the ball gains.
