Work is the product of Force and the Distance that force moves an object. In equation form: W = F * d Work is often measured in Joules (Newton meter), Force in Newtons, and Distance in meters. Energy is the capability of a thing to do work. There are a variety of different forms of energy, and I won't get into all of them here. For the purposes of relating Energy to Work, it usually suffices to talk only about Kinetic Energy. E = 1/2 * m * v^2 m = mass (usually in kg) and v = velocity (in meters / second). E = Kinetic Energy and is usually measured in Joules. The relationship between the two is given in the WorkEnergy formula: W = E1  E2 , where E1 is initial Energy and E2 is final Energy. Power is Work done over Time. P = W / t P = Power in Watts, W = Work in Joules, and t = time in seconds. Units applied are typical of physics problems, but they can be exchanged for other units (Imperial or otherwise) if so required.

simply as my physics teacher puts it: power is the rate at which you do work. energy is the ability to do work.

Power is rate of energy spent per unit time. For example: Watt = A unit of power equal to 1 joule per second; the power dissipated by a current of 1 ampere flowing across a resistance of 1 ohm Here, joule is the unit of energy = the work done when a current of one ampere passes through a resistance of one ohm for one second
