Do Now Give 1 example of potential energy. Learning Objective: I can calculate the amount of work performed by a person or machine. Do Now Give 1 example of potential energy. Give 1 example of kinetic energy.

In science, WORK can be measured. WORK = FORCE x DISTANCE

Work = Using a force to move an object a certain distance. But what is FORCE? http://www.youtube.com/watch?v=_N0r1ignq1w http://www.youtube.com/watch?v=z8ScILNusG4

Force = A quantitative description of the movement of an object.

Have students weight their backpacks with a spring scale.
