Q. In elastic collision,
I. initial kinetic energy is equal to the final kinetic energy.
II. kinetic energy during the collision time $\Delta t$ is constant.
III. total momentum is conserved.
IV. kinetic energy during the collision time $\Delta t$ is not constant. Which of the above statements is/are correct ?

Work, Energy and Power

Solution:

In elastic collision, total momentum and kinetic energy will remain conserved.
