Physics Energy Practice Exam Questions
Energy Practice Exam Questions
Energy is the "stuff" that allows things to happen or change. It's like the fuel in a car that makes it go or the electricity that powers your phone. In physics, we use the term "energy" to describe this ability to make things happen or do work.
