The course
Introductory physics, end to end
36 lessons and 36 simulations across the three semesters most physics sequences run. Each unit stands on its own, and each lesson is built around a simulation you can take apart.
Physics 1
Classical Mechanics
The first semester of university physics, from a cart on a track to a planet around a star.
12 lessons · 12 simulations
Unit 02Waves & Sound
What travels when nothing travels: pulses on a rope, standing patterns that never move, and the pitch a moving siren actually carries.
4 lessons · 4 simulations
Physics 2
Fluids & Thermal Physics
Pressure in a still fluid and a moving one, then what a few hundred molecules in a box have to do with temperature, heat and engines.
5 lessons · 5 simulations
Unit 04Electricity & Magnetism
Fields you cannot see, mapped by what they do, from two point charges to a current conjured out of a moving magnet.
6 lessons · 6 simulations
Unit 05Optics
Light as a ray and light as a wave, and the experiments that decide which description you need.
