The terms work, energy, and power are common words in English. In physics we require precise definitions so that these terms can be formulated mathematically. Readers will find that definitions in physics do not always match the usage of the words. For example, although a student may do ...
Work, Energy and Power are fundamental concepts of Physics. Work is said to be done when a force (push or pull) applied to an object causes a displacement of the object. We define the capacity to do the work as energy. Power is the work done per unit of time. This article discusses...

WEP Work Hooke's Law Power Energy Conservation of EnergyWork, Energy, & PowerWork, energy and power are highly inter-related concepts that come up regularly in everyday life. You do work on an object when you move it. The rate at which you do the work is your power output. When you...
Unit 10 Work, Power, & Energy Work Work is the transfer of energy that occurs when a force makes an object move Work To do work: A force must be applied The motion must be in the same direction as the applied force Work The SI unit for work is Joules or J. The work done on a...
One common unit of energy is the kilowatt-hour (kWh). If we are using one kW of power, a kWh of energy will last one hour. Calculating Work, Energy and Power WORK = W=Fd Because energy is the capacity to do work , we measure energy and work in the same units (N*m or joules)...
The relationship between the terms is clearly determined by their definition.FAQsQ.1. Is the energy amount and work done amount expanded the same?Ans. Energy must be provided to assist the moving of objects and this energy might be portrayed in the type of force. Work done or work is ...
