Newton’s Tube Simulation
Explore gravity and air resistance through this classic physics demonstration.
About This Simulation
This interactive simulation recreates Newton’s famous tube experiment, demonstrating how air resistance affects falling objects. Watch a feather and a pebble fall side by side — first in air, then in a vacuum — and discover what gravity really does when resistance is removed.
