When he is halfway down, his potential energy is halved, his kinetic energy and potential energy are equal and his kinetic energy his halved.
- In physics, an object's kinetic energy is the energy it has as a result of its motion. It is defined as the amount of work required to accelerate a body of a given mass from rest to a certain velocity. The body retains its kinetic energy after gaining it during acceleration until its speed changes.
- Potential energy is stored energy that is affected by the relative position of various components in a system. The potential energy of a spring increases when it is squeezed or stretched. A steel ball has higher potential energy when raised above ground than when it falls to Earth.
- Potential energy is the energy contained in any thing or system due to the position or arrangement of its parts. Kinetic energy, on the other hand, is the energy of moving particles in an item or system.
Thus this is the meaning of kinetic and potential energy.
