A force is any push or pull on an object.

work. When a force is exerted that moves an object you do

The force must be in the same direction as the object’s motion.

Newtons. The unit of measurement for force is

spring scale. The tool used to measure weight or force is a

Joules. The unit of measurement for work is

W = F X d Work = Force X distance Work can be calculated using the following formula:

How much work is done if a force of 20 Newtons moves a box 4 meters? 20N 4 m

W = F X d 20N 4 m W = 20N X 4m W = 80 Joules
