Physics Practice

Eight short, hands-on physics lessons - same expression-editor format as Math Practice, just with formulas pulled straight out of /guides/energy-forces-and-motion and /guides/what-physics-actually-is: Newton's second law, speed, free-fall distance, momentum, and kinetic energy - then three advanced rungs: projectile range (with a trig function and a degrees-to-radians conversion), speed from height via energy conservation, and a momentum-conservation collision capstone. Each lesson gives you a real-world scenario with numbers already substituted in - you write the expression, run it, and get checked instantly.

Your result is checked by rounding it to 4 decimal places and comparing it to the expected answer - you don't need to match decimal formatting exactly, just get the math right.

Start with lesson 1. You can leave and come back any time - your code is saved locally.
