Types of Motion
 

There are four basic types of motion in mechanical systems:
Rotary motion is turning round in a circle, such as a wheel turning.
Linear motion is moving in a straight line, such as on a paper trimmer.
Reciprocating motion is moving backwards and forwards in a straight line, as in cutting with a saw.
Oscillating motion is swinging from side to side, like a pendulum in a clock.
Many mechanisms take one type of input motion, and output it as a different type of motion.
