Physics in Motion and Energy
Bridge the gap between basic concepts and quantitative physics. Calculate trajectories, balance forces, analyze collisions, and explore how energy shapes circuits, waves, and engines.
Like Duolingo, but for Physics in Motion and Energy. Tomo turns the whole topic into a game you play five minutes a day, until it actually sticks.
25 levels across 4 sections, about 50 minutes end to end, roughly 10 days at five minutes a day. It moves through Predicting Motion and Forces in Action; Energy, Momentum, and Collisions; Oscillations, Waves, and Sound; and The Unifying Engines: Fields, Circuits, and Heat. It assumes you already know the basics.

Key ideas in Physics in Motion and Energy
- Gravity acts exclusively along the vertical axis without altering horizontal motion
- Horizontal velocity stays constant during free fall when air resistance is neglected
- Vertical acceleration dictates falling time independently of forward speed
- Time of flight depends entirely on vertical launch velocity and gravitational pull
- Time is the sole scalar parameter shared by both independent motion axes
- Horizontal range equals constant horizontal velocity multiplied by total flight time
- Vertical velocity steadily decelerates by 9.8 m/s every second until apex
- Instantaneous vertical velocity equals zero at the trajectory's maximum altitude
- Symmetric descent mirrors upward motion, returning to launch speed on flat ground
- Decoupled horizontal and vertical velocity components evolve independently under gravity
- Flat terrain yields maximum range at 45 degrees due to balanced speed components
- Launching to elevated ground requires a steeper angle to gain sufficient clearance
- Launching off a cliff favors shallower angles because gravity prolongs fall time
- The geometric area between a velocity curve and time axis yields displacement
- Areas situated below the time axis correspond to backward travel or negative position changes
- Dividing curved or stepped plots into simple geometric shapes reveals net travel
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 in Motion and Energy 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.
You roll a ball off a high table into free fall. Ignoring air resistance, what happens to its forward speed on the way down?
