Torque Lever
Feel why perpendicular force turns most.
τ = rF sin(θ)
Only the perpendicular part of force turns the lever.

A planning file with actual moving examples and live formulas. Each lab follows the same learning loop: predict, change a variable, watch the system respond, and connect the feeling to the equation.
Every physics mini-game should preserve this rhythm. The scene may change, but the learning psychology stays fixed.
The learner chooses a value before seeing the result.
A launch, release, switch, or test button makes the choice visible.
The object moves, bends, falls, glows, focuses, or collides.
The result is shown against the target, expectation, or ideal.
The formula updates live and becomes a memory anchor.
These are not final product components. They are planning-grade prototypes showing how formulas can be rendered, felt, and varied.
The same interaction pattern can cover a large part of school physics if we build reusable engines, not one-off pages.

Planning estimate: 40-50 reusable engines can cover roughly 350-500 physics concepts when variation, difficulty, and assessment layers are added.
