Content

Mechanical energy, also known as motion energy, is how an object moves based on its position and motion. It occurs when a force acts upon an object and the object uses the transferred energy as movement. If an object is moving, it is using mechanical energy. Review the examples of mechanical energy below for where you can see it in your everyday life.
