Work, Force and Energy!
Toy cars made a big impression in physics class this week, but before we began our experiment, we reviewed the concepts of work and force that we have been learning about for the previous two weeks. It is difficult to remember which is which.
Here are the definitions from our textbook:
"Work is what happens when force moves an object."
"A force is any action that changes the location or shape of an object or how fast or slowly an object is moving."
