Force & Work Notes TEKS 6.8E investigate how inclined planes and pulleys can be used to change the amount of force to move an object TEKS 7.7A contrast situations where work is done with different amounts of force to situations where no work is done such as moving a box with a ramp and without a ramp, or standing still
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
