Rotational Dynamics

Experiment #13 from Advanced Physics with Vernier — Mechanics

In this experiment, you will

  • Collect angular acceleration data for objects subjected to a torque.
  • Determine an expression for the torque applied to a rotating system.
  • Determine the relationship between torque and angular acceleration.
  • Relate the slope of a linearized graph to system parameters.
  • Make and test predictions of the effect of changes in system parameters on the constant of proportionality.
