# The students should understand the time period in terms of frequency of oscillation and angular frequency as given by T = 1/ƒ = 2π/ω

## Experiments

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

### The Mathematical Model of Simple Harmonic Motion

Experiment #15 from Advanced Physics with Vernier — Mechanics

In this experiment, you will

• Collect position vs. time data as a mass, hanging from a spring, is set in an oscillating motion.
• Determine the best fit equation for the position vs. time graph of an object undergoing simple harmonic motion (SHM).
• Define the terms amplitude, offset, phase shift, period and angular frequency in the context of SHM.
• Relate the parameters in the best-fit equation for a position vs. time graph to their physical counterparts in the system.
• Use deductive reasoning to predict the system mass required to produce a given value of angular frequency in the curve fit to SHM.
