The first semester of an undergraduate physics course invariably spends a lot of time on two big ideas: The momentum principle and the work energy principle. Both deal with forces acting on an object, ...

The Work Energy Principle is one of the big ideas in introductory physics courses. It's so big that the textbook presentation can get a little confusing - but it doesn't have to be that way. I haven't ...

Kinetic Energy and Potential Energy: We all know that energy can neither be created nor destroyed; it changes its forms. Similarly, kinetic energy also transforms from one form to another. The motion ...

What is the law of conservation of energy? The Law of Conservation of Energy is a fundamental concept in physics that states that energy cannot be created or destroyed in an isolated system; it can ...
