The students should understand that circular motion is caused by a centripetal force acting perpendicular to the velocity

Experiments

Here are experiments our science specialists have selected to support this IB* topic.

Centripetal Accelerations on a Turntable

Experiment #20 from Physics with Vernier

  • Measure centripetal acceleration on a record turntable.
  • Determine the relationship between centripetal acceleration, radius, and angular velocity.
  • Determine the direction of centripetal acceleration.

Circular Motion

Experiment #8 from Physics Explorations and Projects

  • Design and perform an investigation.
  • Draw a conclusion from evidence.
  • Understand that the centripetal force acting on (or the centripetal acceleration of) an object moving in a circular pattern is governed by one of two relationships
