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 potential energy of a conservative force is defined as the negative of the work done by the force in moving from some arbitrary initial position to a new position , i.e. The constant is arbitrary, and the negative sign is introduced by convention (it makes sure that systems try to minimize their potential energy).Work is a fundamental concept in physics that measures the transfer of energy by a force.
