Chapter: 5.0

Work, Power, Energy

In the eyes of a physicist, reading study material is not work. Work is expressed in units of joules. Energy and heat also have the unit of joules. The unit is named after the English physicist and brewer James Prescott Joule, who studied the nature of heat and discovered its connection to mechanical work.

Work, power, energy

Work, power, and energy are very important concepts in physics. These concepts are often used in our everyday lives. In physics, we use them in a slightly different way.

In this chapter we will learn:

  1. What is work in physics
  2. What is energy in physics
  3. What is power in physics
