Physics: Forces, Energy, and Motion
Stop hunting for magic formulas. Learn how vectors, Newton's laws, and energy conservation let you build custom equations for any mechanics problem from scratch.
Like Duolingo, but for Physics: Forces, Energy, and Motion. Tomo turns the whole topic into a game you play five minutes a day, until it actually sticks.
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 Mapping Motion and Forces and Energy Pathways and Problem Translation. It starts from scratch.

Key ideas in Physics: Forces, Energy, and Motion
- Scalars are fully described by just an amount and units, like time or temperature
- Vectors fundamentally require both an amount and a spatial direction to make physical sense, like velocity and force
- Saying '45 seconds north' makes no sense, but 'pushing 10 pounds forward' defines a vector
- Horizontal velocity and vertical gravitational acceleration operate completely independently
- Gravity pulls both objects downward at the exact same rate regardless of sideways motion
- Both objects take the exact same amount of time to hit the ground
- Pulling at an angle splits the pull into two smaller simultaneous effects: moving forward and lifting upward
- The forward pulling force is less than the total pull along the rope because some effort goes into lifting
- Right-triangle geometry separates any single diagonal action into purely horizontal and purely vertical legs
- Perpendicular legs form a right triangle where the hypotenuse represents the actual combined velocity
- You combine perpendicular velocities using the Pythagorean theorem (A² + B² = C²), not simple addition
- A 3 m/s north and 4 m/s east motion creates a true diagonal speed of 5 m/s
- A standard flat grid forces a sliding ramp object to change both horizontal X and vertical Y positions simultaneously
- Tilting the coordinate axes makes the ramp surface the main axis, keeping motion confined to one direction while perpendicular acceleration stays zero
- You are free to tilt coordinate axes in physics whenever it simplifies the problem
- A force requires two interacting objects at that exact moment (contact or field)
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 Physics: Forces, Energy, and Motion 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.
