Question

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

Answer 1

When a body thrown vertically upward its velocity continuously decreases, kinetic energy also decreases. When its velocity becomes zero, its kinetic energy will become zero.

$K.E.=\frac{1}{2}m{v}^2$

According to this equation, when $v$ becomes zero, $K.E.$ will also become zero.
