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 inverted mainly into heat. This heat evolved increases the temperature of the bullet, as well as that of the target.
