9.1 Simple harmonic motion

Experiments

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

Simple Harmonic Motion

Experiment #15 from Physics with Vernier

  • Measure the position and velocity as a function of time for an oscillating mass and spring system.
  • Determine the amplitude, period, and phase constant of the observed simple harmonic motion.
  • Compare the observed motion of a mass and spring system to a mathematical model of simple harmonic motion.

Energy in Simple Harmonic Motion

Experiment #17 from Physics with Vernier

  • Examine the energies involved in simple harmonic motion.
  • Test the principle of conservation of energy.

Pendulum Periods

Experiment #17 from Advanced Physics with Vernier — Mechanics

In this experiment, you will

  • Collect angle vs. time data for a simple pendulum.
  • Determine the best-fit equation for the angle vs. time graph.
  • From an analysis of the forces acting on the pendulum bob, derive the equation describing the motion of the pendulum.
  • Relate the parameters in the best-fit equation for the angle vs. time graph to their physical counterparts in the system.
  • Determine the period of oscillation from an analysis of the angle vs. time graph.
  • Account for the deviation from constant periods when the amplitude becomes large.
