Learn the concepts of work, energy and power in physics with examples, formulas and units. Find out how they are related and how to calculate them using simple steps and diagrams.
Power in mechanical systems is the combination of forces and movement. In particular, power is the product of a force on an object and the object's velocity, or the product of a torque on a shaft and the shaft's angular velocity. Mechanical power is also described as the time derivative of work.
Learn what power is, how to calculate it, and how it relates to work and energy. Explore the concept of power with examples of machines, people, and physics problems.
Power can be expressed in units of watts (W). This unit can be used to measure power related to any form of energy or work. You have most likely heard the term used in relation to electrical devices, especially light bulbs. Multiplying power by time gives the amount of energy.
