Workshop 2. Force and Work

Scientists define energy as the ability to do work. In this session, see how work is defined in physics and examine how energy and work are related.



Program Questions

Answers

1. What are forces and what do they do?

A force is a push or a pull. Forces can transmit energy from one object to another.

2. What is work?

Work equals the force on an object multiplied by the distance the object moves while the force is being exerted.

3. How are work and energy related?

Work is a way of transferring energy from one system to another or converting energy from one form to another.

4. What is power?

Power is the rate at which energy is transferred from one system to another or converted from one form to another.
