I don't know what this means. Hint: Conservation of momentum and energy leads to a very specific conclusion about velocities before and after the collision.
OK.Herzbog said:
Momentum is a physical quantity that measures the motion of an object. It is calculated by multiplying an object's mass by its velocity.
Momentum is a measure of an object's motion, while velocity is a measure of how fast an object is moving and in which direction. Velocity is a vector quantity, while momentum is a vector quantity.
Momentum is conserved in a system of two balls if there is no external force acting on the system. This means that the total momentum of the two balls before and after a collision will remain the same.
Yes, the mass of the balls does affect their momentum. Objects with larger mass will have a higher momentum than objects with smaller mass, assuming they have the same velocity.
An elastic collision is a type of collision in which both kinetic energy and momentum are conserved. This means that the total kinetic energy and total momentum of the two balls before and after the collision will be the same.
