An apple held above the ground has potential energy. As the apple falls, this potential energy is converted to kinetic energy. Finally, the apple hits the ground and stays there. What has happened to the energy? The energy goes to producing sound and to heating the ground, apple, and surrounding air.
It is transformed back into gravitational potential energy.
The apple keeps the energy inside it in the form of mass-energy.
The energy goes into the ground, and as a result, the orbit of the Earth about the Sun is slightly changed.

what was the answer?

the order for strong to weak forces such as

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force

the fundamental forces are those forces that act between to objects or element to make interactions. there are four types of fundamental forces such as strong and weak nuclear forces (due to protons and electrons), electromagnetic force (due to the motion of electrons) and gravitational force (due to orbital movement of the planet). if these forces are arranged on the basis of their maximum strength then the order is

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force
