This does not happen in potential energy. The kinetic energy of a body with the mass âmâ moving at a velocity âvâ is one half the products of the mass of the body and the square of its velocity. i.e., K.E. = (1/2) * m * v2. The average kinetic energy of the atoms or molecules is measured by the temperature of the body.
On a roller coaster, energy changes from potential to kinetic energy and back again many times over the course of a ride. Kinetic energy is energy that an object has as a result of its motion. All moving objects possess kinetic energy, which is determined by the mass and speed of the object. Potential energy is the energy an object has as a result of its position. Potential energy is stored energy that has not yet been released. Gravitational potential energy is potential energy that results from an object's position in a gravitational field, and is equal to the object's weight multiplied by its height. For example, a book placed on a shelf possesses gravitational potential energy because of Earth's gravity.
