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 ...

Solve the classic blob jump physics problem using the Work–Energy Theorem. Follow how gravitational potential energy, kinetic energy, and energy transfer explain the launch speed and maximum height, ...

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 ...

We define and explain mathematically through multiple example problems. Segment 4E: Gravitational Potential and Kinetic Energy Gravitational potential energy and kinetic energy are defined and ...

This is where Emmy Noether, a groundbreaking German mathematician, comes into the picture. She found a breathtakingly simple ...
