Product Summary
The Centripetal Force Pendulum attaches to a Force Sensor and allows students to directly measure the forces involved in circular motion. By attaching the Force Sensor/pendulum combination to the Rotary Motion Sensor, the relationship between force, mass, and velocity in a circular path can be investigated.
How It Works
A sliding mass is used to easily change the effective length of the pendulum, which corresponds to the radius of the circular motion. In addition, drilled masses (not included) can be placed above the sliding mass to change the mass of the pendulum. The cord clip is used to keep the Force Sensor cord from interfering with the motion of the pendulum.
