What is Energy, Work and Power?
Understand the Problem
The question is asking for definitions or explanations of the concepts of energy, work, and power in physics. It requires understanding the fundamental relationships between these three physical quantities.
Answer
Energy is the ability to do work. Work is force applied over a distance. Power is the rate at which work is done.
Energy is the ability to do work. Work is the energy needed to apply a force to move an object a certain distance. Power is the rate at which work is done, or how quickly work is done.
Answer for screen readers
Energy is the ability to do work. Work is the energy needed to apply a force to move an object a certain distance. Power is the rate at which work is done, or how quickly work is done.
More Information
The unit of power is the Watt, which equals 1 Joule per second. Understanding these concepts is fundamental to physics and engineering.
Tips
Students often mix up the definitions of work and power. Work is the amount of energy transferred, while power is the rate of energy transfer.
