How do Scientists
define work?
Work is done when a force changes the
position of an object.
The unit for work is…
Joule (J) = 1Nx 1m
How would you write a formula to
determine work?
James Prescott Joule
Work = Force x Distance
Work
Force Distance
Morty applies a force of 120 Newtons to move his stubborn St. Bernard, Sir Drools A Lot, a distance of 3 meters. How much work did he do?
A force of 350 Newtons is required to move a file cabinet 7 meters to the other side of the room. How much work is done?
How far is a piano moved, by exerting a force of 720 Newtons, 5040 Joules of work are done?
If 9 Joules of work was done to a soccer ball, what force was used to move that ball 3 meters?
