Product Information

Simple and fun to operate, this student-friendly apparatus consists of a 40cm wide disc, driven underneath by a motorized wheel. The disc’s moveable pegs can be positoned a specific distance from the center, and a support rod allows a photogate to be positoned, reading the frequency of the pegs when placed at different positions on the spinning disc. When the frequency of the pegs are measured at different positions, but at a constant rotation, students will find the angular velocity to be consistent, while the linear velocities are very different. The drive motor can also be adjusted, so it can be positioned either near the center of the disk, causing a faster rotation; or near the edge, causing a slower rotation. Activity guide is included. Requires the Photogate System, available separately.
