The universe is made up of matter and energy. Matter â anything that has mass and takes up space â is pretty straightforward and easy to grasp, but energy is a bit more abstract. In physics, energy is the ability to do work, or the ability to move or elicit change in matter.
Kinetic energy is the energy of motion. The word kinetic came from the Greek word âkinesisâ meaning motion. It is the energy an object displays or possesses because of some kind of motion or action. Kinetic energy can also be passed from one moving object to another when a collision or contact takes place.
