28 Δεκ 2020 · Energy is the ability to do work or cause change. It is different from a force. A force is the thing that causes the change, while energy can be thought of as the impetus behind the force. It takes energy in order to apply a force, and applying a force to an object often transfers energy to it. Advertisement.
In physics, we define energy as the ability of something to do work. Energy can exist in many forms. All forms of energy are either kinetic or potential.
