During the central and ealastic impact of two spheres, the difference of their velocities before the impact should be greater than the difference of their speeds after impact.

After the impact, energy is lost which might lead to reduction in velocity.

The central and elastic impact of two spheres, the difference of their velocities before the impact is greater than the difference of their speeds after the impact.

ANSWER:
