Free fall is more than falling down.

Adjust height, initial velocity, and gravity to explore the motion. Try a launch upward: negative velocity means upward.

Equations of motion

v = v₀ + gt

Downward is the positive direction.

Try changing gravity: an object falls more slowly on the Moon. Give it an upward initial velocity and it rises before returning to the ground.
