Physics: How the World Moves
Make sense of the invisible rules governing everyday motion, impacts, and forces. Learn to see how inertia, gravity, and energy dictate why cars slide, roller coasters loop, and collisions happen the way they do.
Like Duolingo, but for Physics: How the World Moves. Tomo turns the whole topic into a game you play five minutes a day, until it actually sticks.
A short one: 11 levels across 2 sections, about 22 minutes end to end, roughly 4 days at five minutes a day. It moves through Reading Everyday Motion and Energy, Impact, and Collisions. It starts from scratch.

Key ideas in Physics: How the World Moves
- An object in motion does not need a continuous push to keep moving
- Without an outside force like friction, air drag, or gravity acting on it, an object's speed and direction remain unchanged forever
- To speed up an object, your push must be stronger than the opposing friction
- When an object moves at a constant, steady speed in a straight line, your forward push exactly balances out the opposing friction force
- Mass measures how stubbornly an object resists any change in its velocity, whether speeding up, slowing down, or turning
- An object with more mass requires a larger force to achieve the exact same change in speed compared to a less massive object
- Mass is not just how heavy an object feels in your hand or how much physical space it takes up
- Friction occurs where the microscopic rough spots of two surfaces catch and drag against each other
- Friction takes kinetic motion and converts it directly into thermal energy (heat)
- Friction is not a built-in property of a single object, but depends entirely on how two contacting surfaces interact
- Gravity pulls all objects downward with the exact same acceleration regardless of their mass
- Lighter or broader objects fall slower on Earth only because air pushes upward against them
- In a vacuum with no air resistance, heavy and light objects fall side by side at identical speeds
- Horizontal velocity and vertical acceleration act completely independently of each other
- Gravity pulls downward at the same rate whether an object is stationary horizontally or moving at high speed
- Gravity in low Earth orbit is still nearly 90% as strong as it is on the surface
