Everyday Mechanics
Understand the physical rules that govern how tools multiply strength, why objects move the way they do, and how machines redirect force. Learn to read the trade-offs of levers, gears, momentum, and balance in the physical world around you.
Like Duolingo, but for Everyday Mechanics. 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 Multiplying Your Force and Predicting Motion and Impact. It starts from scratch.

Key ideas in Everyday Mechanics
- Reducing the effort force required to move a load requires applying that force over a greater distance
- If a tool cuts the effort needed in half, the hands must travel double the distance the load moves
- Mechanical advantage never reduces total work; it trades force for distance
- A lever multiplies force according to the ratio of distances from the pivot point
- Doubling your distance from the pivot doubles the turning force you apply to the other side
- A lighter person can balance a heavier person by moving farther away from the pivot
- An inclined plane spreads the vertical lift over a longer horizontal distance
- A longer, gentler slope reduces the pushing force needed to lift a heavy load
- A steeper ramp shortens the path but demands far more muscle force
- Torque is turning force, calculated by multiplying applied force by the distance from the turning center
- A longer handle increases the distance from the bolt, multiplying turning power without extra arm force
- No simple machine can reduce the total work or energy needed to lift an object to a given height
- Machines repackage work by trading smaller applied force for a longer pulling distance
- Energy cannot be created from nothing by mechanical tools
- A movable pulley divides the total weight among the rope strands supporting the load
- With two supporting strands, you only pull with half the weight of the object
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 Everyday Mechanics 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.
A crowbar lets you lift a boulder with half as much effort. How far do your hands travel compared to the boulder?
