Atwood's Machine

Using an Atwood’s Machine, a photogate is used to measure the velocity of both masses as one moves up and the other moves down. The slope of the graph of velocity vs. time is the acceleration of the system and compensation is made for friction.

Featured Equipment

Comprehensive 850 Mechanics Bundle

This bundle includes all the equipment and sensors needed to perform the experiments in the Comprehensive 850 Mechanics System Experiment Manual.

Super Pulley with Mounting Rod

Super Pulley With Mounting Rod

This Super Pulley mounted on a plastic mounting rod (12.7 mm diameter, 14 cm long) fits most standard laboratory clamps.

Photogate Head

Photogate Head

Monitors the motion of objects passing through its gate, counting events as the object breaks the infrared beam.

Many lab activities can be conducted with our Wireless, PASPORT, or even ScienceWorkshop sensors and equipment. For assistance with substituting compatible instruments, contact PASCO Technical Support. We're here to help.
