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

kinetic energy=1/2mv²
so, if velocity will zero then kinetic energy will also be zero.

Answer 2

As the velocity becomes zero
Velocity = 0 m/s
Kinetic energy = (mv^2)/2 J
Substituting given values, we get
Kinetic energy = m(0)^2/2 = 0 J

Therefore, the kinetic energy becomes zero !
