Work-Energy Theorem
Push a crate and see how forces change its energy in real-time.
The Theorem
The Work-Energy Theorem states that the net work ($W_{net}$) done on an object results in an equal change in its kinetic energy ($\Delta KE$). Work is done when a force causes displacement. Forces in the direction of motion do positive work, while forces like friction do negative work.
The Sandbox
- Use the sliders to set the conditions.
- The Applied Force adds energy (positive work).
- Friction removes energy (negative work).
- Watch how the Net Work bar perfectly matches the Kinetic Energy bar!
