# Simple Harmonic Motion

A humbling fraction of physics boils down to direct application of simple harmonic motion, the description of oscillating objects. Learn the basis for springs, strings, and quantum fields.

**Assumptions and Details**

- The gravitational acceleration is \( g = 9.8 \text{ m/s}^2. \)

What is the frequency of a simple pendulum with arm length \( l = 2.00 \text{ m} \) that is in an elevator accelerating upward at a rate of \( a = 1.00 \text{ m/s}^2\)?

**Assumptions and Details**

- Assume that the amplitude of the simple pendulum is very small.
- The gravitational acceleration is \( g = 9.80 \text{ m/s}^2. \)

**Assumptions and Details**

- The gravitational acceleration is \( g= 9.8 \text{ m/s}^2. \)
- Assume that the amplitude of the pendulum is very small.

The gravitational acceleration is \(g=10\text{ m/s}^2.\)

Assume that \(\sqrt{2} = 1.5 \) and \( \pi = 3 .\) (This is a model of a roly-poly.)

Assume that \( \theta \) is very small.

The moment of inertia on the axis is given by \( I = \frac{3}{2}MR^2. \)

The gravitational acceleration is \(g=10\text{ m/s}^2.\)
