The Rules of the Physical World
Discover the invisible forces that govern everything from your morning walk to the stars above. Learn to see the world through the lens of motion, energy, and gravity.
Like Duolingo, but for The Rules of the Physical World. Tomo turns the whole topic into a game you play five minutes a day, until it actually sticks.
A short one: 9 levels across 2 sections, about 18 minutes end to end, roughly 4 days at five minutes a day. It moves through The Mechanics of Motion and Energy and Impact. It starts from scratch.

Key ideas in The Rules of the Physical World
- Objects in motion stay in motion unless a force acts on them
- Friction occurs when two surfaces slide against each other
- Your body continues moving forward because the brakes only act on the bus wheels
- Friction acts as a resistance that slows things down
- No force is 'pushing' you forward; you are simply resisting the change in speed
- The 'lost' energy of motion is released as heat
- The tendency of objects to maintain their current state of motion (inertia)
- Understanding that friction converts kinetic energy into thermal energy
- To move in one direction, you must apply force to something else in the opposite direction
- Heavier objects (more mass) resist changes in motion more than light ones
- The water pushes the boat forward only because the oar pushes the water backward
- More force is required to accelerate a heavy object
- The relationship between mass, acceleration, and momentum
- Air is a physical substance that objects must move through
- The necessity of an equal and opposite reaction for propulsion
- Objects with more surface area collide with more air particles

Eight weeks. You meant to finish. You didn't.
Tomo gives The Rules of the Physical World the Duolingo treatment: levels, streaks, and quick quizzes that test what you just learned. That game loop is what the tabs above never had, so it's the one you actually finish.
