Before proceeding, be sure you understand the distinctions among force, work, energy, and power. Force exerted on an object over a distance does work. Work can increase energy, and energy can do work. Power is the rate at which work is done.

Work, Energy, and Power. Lesson 1 - Basic Terminology and Concepts. Definition and Mathematics of Work. Calculating the Amount of Work Done by Forces. Potential Energy. Kinetic Energy. Mechanical Energy. Power. Lesson 2 - The Work-Energy Relationship.
Work is the energy needed to apply a force to move an object a particular distance, where force is parallel to the displacement. Power is the rate at which that work is done.
Energy. is the capacity for doing work. You must have energy to accomplish work - it is like the "currency" for performing work. To do 100 joules of work, you must expend 100 joules of energy. Power. is the rate of doing work or the rate of using energy, which are numerically the same.
Power is the rate at which work is done on a system or the rate of energy transfer between systems. Rate refers to the amount of change in some measure of time. 1 Watt = 1 Joule/Second
So firstly, power is the rate at which energy is transferred or the rate at which work is done. Secondly, the first equation to calculate power is: power equals energy transferred,...
Explain work as a transfer of energy and net work as the work done by the net force. Explain and apply the work-energy theorem.
