In review, energy is the capacity to do work, and work is accomplished when a force moves an object. Energy exists in different forms, all of which can be classified as either potential energy or kinetic energy. Potential energy is energy stored in an object due to its position or arrangement. Kinetic energy is energy of an object due to its movement-its motion. All types of energy can be transformed into other types of energy. This is true for potential and kinetic energy as well. Potential energy can be converted into kinetic energy, and kinetic energy can be converted into potential energy.
Mechanical energy is the sum of energy in a mechanical system, or any group of objects that interact based on basic mechanical principles. This includes both kinetic energy, the energy of motion, and potential energy, the stored energy of position.eneral Background. Mechanical energy exists as both kinetic and potential energy in a system. Kinetic energy is present whenever an object is in motion. Potential energy is based on the position of an object; it is stored energy, and cannot do work on its own.
