How the World Moves
Like Duolingo, but for How the World Moves. Tomo turns the whole topic into a game you play five minutes a day, until it actually sticks.
For the part of you with thirty open tabs that never became anything.
A short one: 12 levels across 2 sections, about 24 minutes end to end, roughly 5 days at five minutes a day. It moves through The Rules of Motion and Gravity and Energy. It starts from scratch.

Key ideas in How the World Moves
- Objects do not 'want' to stop; they want to keep their current velocity
- Higher mass makes an object harder to start or stop
- Stopping or starting requires an external push or pull
- Mass is independent of gravity but dictates resistance to motion
- Motion doesn't wear out over time
- Shaking or pushing an object reveals its mass through its 'stubbornness'
- The tendency of objects to maintain their current state of motion
- Mass as a measure of resistance to change
- The passenger and the car are two separate objects with their own inertia
- Stopping the car does not automatically stop the passenger's forward motion
- A seatbelt provides the external force needed to change the passenger's state of motion
- Your body is trying to stay at rest while the floor moves under you
- The 'push' is actually the bus moving forward while you stay put
- Inertia makes your body resist the sudden change in speed
- Without air resistance or gravity, there is no force to change the ball's path
- The independent motion of a passenger vs. a vehicle
You've tried the other tabs
Thirty open tabs. Four facts you actually kept.
You watched. You nodded. By Sunday it was gone.
One answer, then back to scrolling.
Eight weeks. You meant to finish. You didn't.
Tomo gives How the World Moves 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.
Here's what playing it feels like
A real question from this course. Take your best guess.
If a bowling ball and a tennis ball are both sitting still, why is the bowling ball harder to get moving?
