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, and energy are very important concepts in physicsPhysics is the scientific study of matter, energy, space, and time, and of the relations between them.. 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:
5.1
In physicsPhysics is the scientific study of matter, energy, space, and time, and of the relations between them., work is understood only as physical activities under certain conditions. Thinking, for example, would therefore not be doing work in physics. Work involves the application of a force over a distance.
