Important Update: Touch support restored for interactive simulations
Touch support has been restored for all interactive simulations. Draggable elements now work properly on modern smartboards, Promethean boards, and Windows touchscreen devices.

Quick update for iOS users: all Physics Zone simulations now run smoothly on iPhones, iPads, and Macs after fixing the full-screen toggle issue.
This simulation models Newton’s tube experiment, showing how air resistance affects falling objects. By removing air from the tube and flipping it, users can observe how a feather and a pebble fall differently in air but identically in a vacuum—demonstrating that gravity accelerates all objects equally when air resistance is removed.
