Can somebody me change these sentences into different words? 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, the object speeds up and thereby gains kinetic energy. kinetic energy is a property of a moving object or particle and depends not only on its motion but also on its mass. the kind of motion may be translation (or motion along a path from one place to another), rotation about an axis, vibration, or any combination of motions.
