Gravity / Free-Fall
Drop an object from a chosen height and watch gravity accelerate it — adjustable g, height, and mass (mass turns out not to matter).

What you can adjust
- Gravity (g)
- 1 – 25 m/s²
- Drop height
- 0.1 – 200 m
- Mass
- 0.01 – 1000 kg
- Bounciness (restitution)
- 0 – 1
Teachable point: in a vacuum, mass doesn't change fall time or impact speed — try it.
0 = stops dead on impact, 1 = bounces forever with no energy lost.
About this simulation
What it shows
An object is dropped from a chosen height and falls under constant gravity with no air resistance. You can make it bounce when it lands.
The key idea
Every object speeds up at the same rate, g, so the fall takes t = √(2h/g) whatever the mass. Height h and gravity g are the only things that matter.
Try this
Change Mass from 1 kg to 1000 kg and drop it again: the fall time and the impact speed do not change.
The fall happens in a vacuum, so there is no air drag. Bounciness only changes what happens after the first impact.
