Build energy one idea at a time.
Start with the foundations, then explore advanced ideas and calculus at the depth your course needs.
5 of 5 lessons
Kinetic Energy
Connect mass and speed to the energy carried by motion.
Gravitational Potential Energy
Measure the energy change associated with height in a gravitational field.
Elastic Potential Energy
Link spring deformation, restoring force, and stored energy.
Energy Conversion & Conservation
Track kinetic, potential, thermal, and other stores without losing the total.
Energy Calculus Integration
Read work as an integral and force as the slope of potential energy.
Change one variable. Watch the physics respond.
Explore K = ½mv², then take the idea into the full lessons.
See how speed changes energy
Kinetic energy grows with speed squared, not speed alone.
Everything around the chapter, in one place.
Keep building with practice, classroom presentations, formulae, and a game that puts these ideas to work.

Start with kinetic energy, then add gravitational and elastic stores. Conservation and calculus explain how the pieces connect; the final mission combines them.
Move without losing your place.
