Setups other learners found interesting in Ball Gravity. Try one, then tweak it.
A ball falls under gravity, bounces off the floor and loses a little energy on every impact. Adjust the gravitational acceleration, the ball's mass, the wind, the friction and the restitution to see how each one changes the motion. It connects free fall, Newton's laws and the coefficient of restitution in a single scene.
In free fall every object accelerates at g ≈ 9.81 m/s², whatever its mass. Equations, gravity on other worlds, and how air resistance sets terminal velocity.

A bouncing ball loses speed at each impact, keeping a fraction e (restitution). Every bounce reaches e² of the last height — the maths, with a simulation.
