kinetic energy= ½mv²
potential energy= mgh
power = energy/ time
work done = FS
hope this helps u
potential energy= mgh
power = energy/ time
work done = FS
hope this helps u

Conservative force - Any force which conserves mechanical energy, as opposed to a nonconservative force. See statement of conservation of mechanical energy.
Conservative System - A system in which energy is conserved.
Energy - The ability to do work.
Kinetic Energy - The energy of motion.
Nonconservative Force - Any force which does not conserve mechanical energy, as opposed to a conservative force.
Path independence - Property of conservative forces which states that the work done on any path between two given points is the same.
Potential energy - 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.
Work - 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.
Joule - The units of work, equivalent to a Newton-meter. Also units of energy.
Power - Work done per unit time. For formulas, see Formula for average power, Definition of instantaneous power, and formula for instantaneous power.
Watt - Unit of power; equal to joule/second.
Formulas
Work done by a constant force parallel to displacementW = Fx
Work done by any constant forceW = Fx cosθ
Work-Energy TheoremW = ΔK
Formula for average power=
Definition of instantaneous powerP =
Formula for instantaneous powerP = Fv cosθ
Work done by a position-dependent forceW =F(x)dx force.
Definition of potential energy.ΔU = - W
Gravitational potential energy.UG = mgh
Statement of conservation of mechanical energy.Δ(U+K) = 0
Definition of total mechanical energy.U + K = E
Definition of potential energy given a position-dependent force.ΔU = -F(x)dx
