a ball is thrown vertically upward and its velocity keeps on changing. What happen to the KE when its velocity will be zero?

kinetic energy depends on mass and velocity.
K.E.=1/2mv2
so if v=0 then K.E.=0

Hello friend

Kinetic energy is the energy possessed by the body when it is in motion. Kinetic energy comes into play only when an object is in motion

Kinetic energy = (1/2)mv²

When a body is projected upwards, its velocity starts decreasing. So even the kinetic energy starts decreasing.

When the body reaches the max height its velocity becomes 0, so the kinetic energy becomes 0.

KE=1/2*m*0²=0

But he potential energy increases because of the increase in height

Once the body starts descending down, it's velocity increases and even the kinetic energy.

Hope it helps!!
