Gravity & Freefall
Atwood’s Machine
Atwood’s MachineTwo Super Pulleys mounted on a long rod produce a classic, low-friction introduction to Newton’s Second Law.
Constant Speed Buggy
Constant Speed BuggyTurn on the buggy and let it go. When it reaches a wall, it flips over and changes direction.
Discover Freefall System
Discover Freefall SystemWith a magnetic release and a Time of Flight pad this system minimizes human error and allows detailed investigation of air resistance and gravity.
Free Fall Apparatus
Free Fall ApparatusThe acceleration of gravity g can be computed by measuring the drop distance and the fall time. The apparatus consists of a release mechanism that also acts as the start switch, a switch plate that acts as the stop switch, and conducting balls.
