Mechanical energy is the sum of kinetic and potential energy in an object. It is energy in an object due to its motion, position, or both. How does the total mechanical energy respond as kinetic energy and potential energy change? Why?
Mechanical energy is made when something is moved. The energy that is moving is kinetic. And potential energy is stored energy. Mechanical energy can be used to store energy and to cause moving energy. For instance: a slingshot. Pulling back the band creates potential energy and releasing it creates kinetic energy.
