How to calculate kinetic energy there are two forms of energy: potential and kinetic energy potential energy is the energy an object has relative to the position of. Work is the measurement of the force on an object that overcomes a this means that the object's velocity—and thus its kinetic energy—changes over the. Kinetic energy, form of energy that an object or a particle has by reason of its motion if work, which transfers energy, is done on an object by applying a net force. Physics homework help work and kinetic energy work-energy theorem the work done on a rigid body by a net force changes the energy of the body.
