What is the difference between mechanical and nonmechanical energy

The total mechanical energy of Lee Ben Fardest is the sum of the potential and kinetic energies. The two forms of energy sum up to 50 Joules. Notice also that the total mechanical energy of Lee Ben Fardest is a constant value throughout his motion. There are conditions under which the total mechanical energy will be a constant value and conditions under which it will be a changing value.

This is the subject of Lesson 2 - the work-energy relationship. For now, merely remember that total mechanical energy is the energy possessed by an object due to either its motion or its stored energy of position.

The total amount of mechanical energy is merely the sum of these two forms of energy. And finally, an object with mechanical energy is able to do work on another object. Physics Tutorial. My Cart Subscription Selection. Student Extras. Next Section: Power.

If an object is moved, then work has been performed. Work requires three things: a force, a displacement and a cause. For example, if you picked up a book and placed it on the top shelf of a bookshelf, the force would be you lifting the book, the displacement would be the movement of the book and the cause of the movement would be the force you applied.

There are two types of energy: potential and kinetic. Potential energy is energy that is stored in an object due to its position. This type of energy is not in use but is available to do work. For example, the book possesses potential energy when it is stationary on the top of the bookshelf. Kinetic energy is energy that is possessed by an object due to its motion.
