Which of the following statements about collisions is true?
A)Total momentum is conserved in elastic,but not in inelastic collisions.
B)Total kinetic energy is conserved in elastic,but not in inelastic collisions.
C)Total kinetic energy is always conserved.
D)In totally inelastic collisions,all of the kinetic energy is lost.
E)In totally inelastic collisions,all of the momentum is lost.

Question

Quizplus · Accepted Answer

In elastic collisions, both total momentum and kinetic energy are conserved. In inelastic collisions, total momentum is conserved but total kinetic energy is not. Total kinetic energy can either increase or decrease depending on the type of inelastic collision. In totally inelastic collisions, kinetic energy is not conserved and is converted into other forms such as heat or sound. However, total momentum is still conserved in such collisions.
