Quarter-pipe ramp
A curved ramp 1.5 m high, a quarter circle, 30 kg: a ball rolling into it runs up the curve and comes back, or flies off the top if it is fast enough (v² > 2gh, or 10/7 gh rolling).
Funnel
A V-shaped funnel 1.2 m across with an outlet 0.2 m wide, 5 kg (two walls welded together): it gathers balls and lets them out one by one. Pin or weld it in place.
Car with suspension
A 120 kg body on two 10 kg wheels, each on a spring (3500 N/m) and a damper (ζ ≈ 0.4) in a vertical guide: drive it over bumps, change the damping and compare.
Cup (U channel)
A U-shaped cup 0.8 m wide and 0.5 m deep with 0.08 m walls, 4 kg: balls dropped in stay in it, and it can be carried or tipped.
Cart on two wheels
A 3 kg cart 0.8 m long on two 0.2 kg wheels, each on a pin axle: put a load on it, pull it with a cable, give it a motor.
Script
Energy audit of the open scene
Open any scene, then run it: kinetic and potential energy of every moving body, their sum, and how much was lost.
Script
The rocket equation
A rocket that burns fuel gets lighter: Δv = v_e ln(m₀/m) − gt, mass and thrust set from the script.
Script
Elastic collisions for every mass ratio
A moving ball hits balls of 0.25 to 8 times its mass; the speeds after against the formulas.
