Any force which conserves mechanical energy, as opposed to a nonconservative force. See statement of conservation of mechanical energy.
A system in which energy is conserved.
The ability to do work.
The energy of motion.
Any force which does not conserve mechanical energy, as opposed to a conservative force.
Property of conservative forces which states that the work done on any path between two given points is the same.
The energy of configuration of a conservative system. For formulae, see Definition of potential energy, gravitational potential energy, and Definition of potential energy given a position-dependent force.
Total mechanical energy
The sum of the kinetic and potential energy of a conservative system. See definition of total mechanical energy.
A force applied over a distance. For formulas, see work done by a constant force parallel to displacement and work done by any constant force, and work done by a position-dependent force.
The units of work, equivalent to a Newton-meter. Also units of energy.
Work done per unit time. For formulas, see Formula for average power, Definition of instantaneous power, and formula for instantaneous power.
Unit of power; equal to joule/second.
