Question

A body is thrown vertically upward. Its velocity keeps on decreasing. What happens to its kinetic energy as its velocity becomes zero?

Answer 1

As the body moves upward, its velocity decreases, so its kinetic energy also decreases.

At the highest point, the velocity becomes zero. Therefore,

K.E. = `1/2 m v^2`

= 0

So, the kinetic energy becomes zero and is converted into gravitational potential energy.
