Overview

Today's lesson is a topic from the calculus of physics, work. A force is applied to an object causing it to move a distance. Work is the product of the force and the distance. If the force is constant, this is an easy algebra problem. However variable force requires integration so calculus comes into play.

Objectives

By the end of this topic you should know and be prepared to be tested on:

• 7.1.1 Understand and be able to calculate common units of measure for force and work (newtons, joules, etc.)
• 7.1.2 Set-up and solve a problem involving work done by a constant force or variable force
• 7.1.3 Set-up and solve a problem involving work done stretching/compressing springs (Hooke's Law)
• 7.1.4 Set-up and solve a problem involving work done pumping liquids from containers

Terminology

Define: Newton, Joule, force, constant force, variable force, work, Hooke's Law
