What is mechanical energy?

Mechanical energy is different from kinetic or potential energy, even though they are connected and work together to get work done. Find out what mechanical energy is. read more

Mechanical energy is the sum of kinetic and potential energy in an object that is used to do work. In other words, it is energy in an object due to its motion or position, or both. In the 'open door' example above, I possess potential chemical energy (energy stored in me), and by lifting my hands to push the door, my action also had kinetic energy (energy in the motion of my hands). read more

In physical sciences, mechanical energy is the sum of potential energy and kinetic energy. It is the energy associated with the motion and position of an object. The principle of conservation of mechanical energy states that in an isolated system that is only subject to conservative forces, the mechanical energy is constant. read more

Energy is the ability to do work, where work is the movement of an object when a force is applied to it. read more
