## Motion

Motion is the acceleration, displacement, or velocity of an object relative to a given frame of reference.  There are four basic types of motion with each one moving different than the other.  There is a you could say a fifth called irregular motion.

### Types of Motion

• Linear motion is anything that moves in a straight line.
• Oscillator motion moves repeatedly back and forth.
• Rotary motion is anything that moves in a circle.
• Reciprocating motion moves backwards and forwards in a straight line.
• Irregular motion is any motion that has no fixed pattern.

## Linear Motion

### Linear Motion Formula

$$x = \bar {v} t$$

Where:

$$x$$ = position (linear motion)

$$\bar {v}$$ = averave velocity

$$t$$ = time

## Rotational Motion

### Rotational Motion Formula

$$\theta = \bar {\omega} t$$

Where:

$$\theta$$ (Greek symbol theta) = angular position (rotational motion)

$$\bar {\omega}$$ (Greek symbol omega) = averave angular velocity

$$t$$ = time
