Example of Kinetic Energy

Kinetic energy is represented by the mathematical formula K=mv2. This means kinetic energy equals the mass of an object, times its velocity squared. The original formula was discovered by Newton, but misinterpreted as K=mv. The additional 'squared' was deduced by French scientist and mathematician Madame Marquise Emilie du Chatelet, from observations of experiments in France. This formula became the basis for the Theory of Relativity as expounded by Einstein, who used the formula to define c as the speed of light to define atomic energy.

Examples of Kinetic Energy:

K=10x100= 1,000. A mass of ten, traveling at a speed of ten2, has a kinetic energy of 1,000.

The cars of a roller coaster reach their maximum kinetic energy when at the bottom of their path. When they start rising, the kinetic energy begins to be converted to gravitational potential energy. The sum of kinetic and potential energy in the system remains constant, when neglecting (relatively small) losses to friction.
