Physics of Motion and Energy
Move beyond plug-and-chug formulas to analyze the hidden budgets of the physical world. Learn how momentum, rotational inertia, energy landscapes, and entropy govern everything from vehicle collisions to orbital mechanics.
Like Duolingo, but for Physics of Motion and Energy. 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 Predicting Motion: Momentum and Spin and Tracking Energy: Fields and Heat. It assumes you already know the basics.

Key ideas in Physics of Motion and Energy
- Internal forces between parts cannot alter the total system momentum
- Total momentum changes only when an outside net force acts on the system
- Explosion forces push parts oppositely with zero net gain in total momentum
- Stopping a vehicle requires a fixed total impulse to clear its momentum
- Extending the duration of deceleration dilutes the peak force on the cabin
- Rigid materials halt motion almost instantly, spiking peak impact force
- Elastic collisions preserve total translational kinetic energy entirely
- Inelastic collisions divert kinetic energy into heat, sound, and shape change
- Objects locking together after impact represents maximal kinetic energy loss
- Opposing momentum pulses share identical magnitude in an isolated pair
- Recoil velocity scales inversely with the object's relative mass
- The heavier object moves away with a proportionally smaller speed
- Internal explosive forces cancel out and cannot alter center-of-mass motion
- Gravity acts as the sole external force guiding the collective trajectory
- The combined center of mass follows the original parabolic arc to the ground
- Rotational inertia scales with the square of the distance from the pivot.
