You get to explore the concepts of work and power. Investigate the work-energy theorem and learn how to solve problems.
After completing this tutorial, you will be able to complete the following:
What is work?
~ Work is force through a distance, therefore work = force x displacement.
What is power?
~ Power is the amount of work done per unit time.
What units of measurement are used to gauge work and power?
~ Work is measured in units called joules. Power is measured in units called watts.
If an elevator does 1,000 joules of work in 5 seconds, how many watts of power are produced?
~ If an elevator does 1,000 joules of work in 5 seconds, 200 watts of power are produced.
