Energy
The ability to do work, which is the ability to exert a force causing displacement of an object.
Power
Power is the amount of energy transferred or converted per unit time. It is given by the formula: P=ΔW/Δt where ΔW = change in work done and Δt = change in time
Work
Results from the application of force over distance. When work is
done, energy is transformed from one form to another.
