Go Direct® Centripetal Force Apparatus (VR158128)



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.

Sample Data

Go Direct® Centripetal Force Apparatus Sample Data

Applying a curve fit to the raw data will provide students with clues to the nature of this relationship.

Go Direct® Centripetal Force Apparatus Sample Data

Linearized data for a rotating mass. What are the units of the slope of the line? Can your students predict the mass given the position on the beam?
