**The formula for kinetic energy is K.E. = 1/2 mv ^{2}, where "m" stands for mass and "v" stands for velocity.** Kinetic energy is typically measured in units of Joules, and 1 Joule is equal to 1 kilogram-meters squared per second squared.

Energy is usually divided into two types by chemists. Kinetic energy is the energy that occurs in an object in motion. Examples of kinetic energy include the planets revolving around the sun and a person walking down a street. Potential energy is the energy an object possesses because its position relative to another object. An example of potential energy is a person standing at the top of a staircase.
