Chemical Energy --Chemical energy is a form of potential energy related to the breaking and forming of chemical bonds. It is stored in food, fuels and batteries, and is released as other forms of energy during chemical reactions. Mechanical Energy -- Energy of the moving parts of a machine....
1. What is potential energy? Potential energy is the energy that an object possesses due to its position or configuration. It is stored energy that has the potential to be converted into other forms of energy, such as kinetic energy.

Kinetic Energy and Work; Potential Energy;Conservation of Energy. Lecture 07 Thursday: 5 February 2004 WORK Work provides a means of determining the motion of an object when the force applied to it is known as a function of position. For example, the force exerted by a spring varies with ...
We should properly speak of “the elastic potential energy of the block-spring system” or “the gravitational potential energy of the ball-Earth system”, not “the elastic potential energy of the spring” or “the gravitational energy of the ball”. • How to get the absolute value of ...
How to Calculate Mechanical Energy Add the kinetics energy and the potential energy together! Mechanical Energy = Kinetic Energy + Potential Energy ME = KE + PE ME = ½ mv2 + mgh Mechanical Energy For a falling object: GPE decreases because height decreases KE increases because gravity increas...
A hammer has mechanical energy:when raised up it has potential energy (the energy of position) when falling down it has kinetic energy (the energy of motion)Energy goes from one storage to another, or goes to heat:Heat is a type of energy, too. In fact the total amount of energy ...
