Potential energy is the stored energy of an object that has the potential to change to a different form of energy to do work. The types of potential energy are gravitational, elastic, chemical, electric and nuclear. More »

More than three types of energy exist, but a few examples of energy types include mechanical, heat and electrical energy. These describe the energy of motion that does work, the energy of being pushed into motion by heat... More »

Energy is transferred through conduction, convection or radiation. There are many forms of energy, but these are the only three ways in which energy is transferred to another object. More »

Elastic potential energy is the energy stored from an elastic object being stretched or compressed. It equals the amount of work that was done to stretch the object. The equation for elastic potential energy is PE=1/2kx2... More »

Gravitational potential energy depends on the mass of the object, acceleration because of gravity and the height of the object from a zero position, which is typically the ground or surface where the object is resting. T... More »

An object's gravitational potential energy is equal to the product of the object's mass times the gravitational field strength times its height (PEgrav = mass * gravity * height). The strength of Earth's gravitational fi... More »

The work-energy theorem is a generalized description of motion that states that the work done by the sum of all forces acting on an object is equal to the change in that object's kinetic energy. This principle of work an... More »
