Question

Difference between potential and kinetic energy with the help of an example

Answer 1

Kinetic energy is energy associated with the motion of some mass - if the mass is at rest, there is no kinetic energy.
If a body of mass m is moving with speed v then kinetic energy KE=1/2×mv^2

Potential energy is energy associated with the position of some mass in a force field - it is energy that may be converted to kinetic energy if the mass is free to move.

When we throw a mass upward , we give some kinetic energy to the body.
And it converts it's kinetic energy to potential energy. After some time the body get maximum potential energy when the kinetic energy is zero that is the velocity is zero.
Again the body falls downward and this time it's potential energy converts to kinetic energy.
