Digital Laboratory // Free Fall Bench

Physics Lab: Gravity, Drag, and Free Fall

Compare two test bodies under the same planetary gravity. In a vacuum, both bodies accelerate at the exact same rate. In air, this lab applies a simple drag coefficient so higher-drag shapes fall more slowly.

Vacuum s = 1/2 g t^2 v = g t Air model a_eff = g * (1 - Cd)

Planet: Earth Vacuum

Planetary gravity

Environment

Vacuum Air

Vacuum keeps acceleration identical for both bodies. Air enables each object's drag coefficient.

Drop height 12.00 m

Gravity 9.80 m/s^2

Model Ideal vacuum

Test Chambers

Drop two bodies side by side

Both chambers start from the same height and use the selected planet's gravity.

Vacuum mode uses the exact same acceleration for both bodies, so only their appearance changes, not the kinematics.
