When a ball rolls down a hill and gains momentum is the law of momentum conservation violated?
No it is not! The hill is moving in the opposite direction.
You do not perceive the motion of the hill since it move sooo slowly...
When the ball will stop with respect to the hill (for instance because of an obstacle rigidly connected to the hill) then the hill will stop too.
And the potential energy of the ball will be transformed into heat and sound.
What else can I help you with?
What kind of energy does the can gain as it rolls back to you?
it gains kinetic energy as the can rolls back to you.
What are examples of potential energy and kinetic energy in bowling?
In bowling, the potential energy is the stored energy in the ball as it sits at the top of the lane before the bowler releases it. The kinetic energy is then seen as the ball gains speed and momentum as it rolls down the lane towards the pins.
A freight train rolls along a track with considerable momentum If it were to roll at the same speed but had twice as much mass it's momentum would be?
The momentum would be twice as much. Momentum is directly proportional to mass, so if the mass doubles while the speed remains the same, the momentum will also double.
Does gravity stop a ball from rolling?
Momentum is the product of mass and velocity. When an object slows down, the object reduces in velocity. Since Mass is constant, when velocity reduces momentum reduces. thus momentum can be what stops a rolling object. However, a resistive force the reason for the reduction of velocity and subsequently halting.
What energy conservation occurs when a ball rolls down a hill?
When a ball rolls down a hill, potential energy is converted into kinetic energy. As the ball moves downward, its potential energy decreases while its kinetic energy increases. This is an example of the conservation of mechanical energy, where the sum of potential and kinetic energy remains constant in the absence of external forces like friction.
What if your friend says that the law of conservation of momentum violated when a ball rolls down a hill and gain momentum what do you say?
it could be said that since potential energy (mgh) is lost at the exact rate kinetic energy (ke) is gained, that energy is translated into another form since force applied (gravity) over time then impulse applied and increase of momentum
If a moving ball rolls into a stationary ball the total momentum of both balls after the collision will be?
By the Law of Conservation of Momentum, the total momentum after the collision must be the same as the total momentum before the collision.
What kind of energy does the can gain as it rolls back to you?
it gains kinetic energy as the can rolls back to you.
A cart gains energy as it rolls down hill what is the force that does the work?
Gravitational force.

A golf ball hits a tennis ball The golf ball stops but the tennis ball rolls away What kind of example is this Grvitaion Conservation of momentum Equal and opposite forces or velocity?
It depends on whether they are both moving or if one is stationary and the other is moving.

When a ball rolls down a hill what energy conversion occursng?
As the ball rolls down the hill, potential energy is converted into kinetic energy. The higher the hill, the more potential energy the ball has, which is converted into kinetic energy as it gains speed while rolling downhill.
When a ball rolls down a hill what energy occurs?
The situation is similar as when an object falls. Potential energy is converted to kinetic energy (including rotational energy in this case); part of that kinetic energy is converted to heat energy.
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.
