Flashcards in Simple Harmonic Motion Deck (17):

1

## Amplitude

### Maximum displacement

2

## Time Period

### Time for one complete oscillation

3

## Frequency

### Number of oscillations per second

4

## Angular frequency

### 2π x frequency

5

## Phase difference

### An angular measure of how much one oscillation leads or lags another

6

## Simple harmonic motion

###
When the acceleration is proportional to displacement

Acceleration occurs he the opposite direction to displacement

7

## Useful damping

###
Bridges

Car suspension

8

## Damping problems

### Anything which requires an oscillator to maintain a fixed ampmitude

9

## What is the gradient of a displacement graph equal to?

### The velocity

10

## Displacement

### Distance of a body moved from its equilibrium

11

## equation defining simple harmonic motion

### a = - (2πf)^2x

12

## equations for displacement

### x= Acos(2πft) or x= Asin(2πft)

13

## equation for Vmax

### Vmax = (2πf)A

14

## How is the time period related to amplitude of oscillations

### Time period and Amplitude are independent
