Friction and Newton's Laws

Coefficients of static friction and kinetic friction are determined for a block connected by a string over a pulley to a hanging mass.

Static friction is studied by first finding the maximum value the hanging mass can have while the block remains at rest. Kinetic friction is examined by using the Photogate to measure the velocity of the block as it slides along the track. The slope of the velocity vs. time graph gives the acceleration of the system.

Featured Equipment

550 Universal Physics System

Universal 550 Physics Experiment Bundle

This system provides a complete set of labs for mechanics, heat, light, sound, and electromagnetism.

550 Universal Interface

550 Universal Interface

The 550 is fast, powerful, and incredibly affordable. It offers half the ports and many of the same features as our 850 Interface in a smaller package.

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.
