Question
given the collision between two objects, only one of the following statements is always true regarding energy and momentum before and after the collision. which one is it, and why?
I. momentum and kinetic energy are both conserved
[3 pts] Given the collision between two objects, only one of the following statements is always true regarding energy and momentum before and after the collision. Which one is it, and why? i. ii. iii. Momentum and kinetic energy are both conserved Kinetic energy is conserved, but momentum is not conserved. If no other forces act on the two objects (except those on each other), momentum is always conserved, but energy is not necessarily conserved.Explanation / Answer
In this question the third statement is true, as kinetic energy is not always conserved. It is conserved only in the case of elastic collision. In in-elastic collision kinetic energy does not conserve but gets transferred into another forms of energy.
