Go Direct® Centripetal Force Apparatus

Go Direct® Centripetal Force Apparatus product image

The Go Direct Centripetal Force Apparatus and Go Direct Force and Acceleration Sensor (not included) make an ideal combination to explore rotational dynamics.


When students use the Go Direct Centripetal Force Apparatus with a Go Direct Force and Acceleration Sensor, they can conduct a variety of rotational dynamics investigations with a single experiment setup. This combination easily measures angular velocity and centripetal force and acceleration without the hassle of wires.

Go Direct Centripetal Force Apparatus can be used in a variety of experiments:

  • Investigate circular motion by measuring centripetal acceleration in relation to the radius of rotation and angular velocity.
  • Explore rotational dynamics through an investigation of the force required to keep a mass in circular motion.
  • Explore Newton’s second law, angular acceleration, and the moment of inertia as they relate to circular motion.
