A bullet becomes hot on hitting a target. Why?

Text Solution

Verified by Experts

A bullet is obstructed when it hits a target. As a result of the impact, the kinetic energy of the bullet is converted mainly into heat. This heat evolved increases the temperature of the bullet, as well as that of the target.
