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 ...

The film discusses the revolutionary impact of the fiberglass pole in pole vaulting, highlighting its ability to improve performance through efficient energy conversion. It explains how the extreme ...

Step into our online science lab and learn more about states of matter. Interact with the activity to see what happens when different substances change state. There are three main states of matter: ...

Potential energy is the latent energy in an object at rest, and is one of two forms of energy. The other form, kinetic energy, is the energy expressed by an object in motion. Potential energy is a ...

Potential energy is stored energy. Potential energy is the energy that exists by virtue of the relative positions (configurations) of the objects within a physical system. This form of energy has the ...
