PASCO Dynamics Cart

A PASCO cart on a track with a motion sensor displays real-time position, velocity, and acceleration graphs simultaneously. Students see the derivative/integral relationships between kinematic quantities as the cart moves.

Air Track

A nearly frictionless glider on an air track demonstrates constant velocity motion (Newton's First Law) and elastic collisions. The track is marked at regular intervals for quantitative measurement of position …
Two sequential frames of the air track with yellow position markers (-5 to 5), a photogate, and digital display reading 48 ms (top) and 17 ms (bottom), with glider visible as motion blur

Air Track with Photogates

Photogates on a nearly frictionless air track measure instantaneous and average velocity with millisecond precision. Students see the operational distinction between these two velocity concepts and learn how flag width …
