You will 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 power?
~ Power is the amount of work performed over a given period of time.
What type of quantity is power?
~ Power is considered to be a scalar quantity which means it has magnitude but no direction, unlike vector quantities.
In the SI system of units, what unit is used to measure power?
~ In the SI system of units, power is measured in Watts.
Based on the equation for finding the average of power, what would be the power equivalent of 1 joule of work per second?
~ One joule of work per second would be equal to 1 Watt of power.
