Types of Movement
Design & Technology: AQA GCSE, topic 1.5.1
Different Types of Movement
There are four main types of motion (movement) in mechanical devices: linear, rotary, reciprocating and oscillating.
Linear motion
- Motion in a straight line in one direction.
- E.g. A train.
Rotary motion
- Motion in a circular motion around a central pivot point.
- E.g. A children’s roundabout.
Reciprocating motion
- Backwards and forwards motion in a straight line.
- E.g. A bicycle pump.
Oscillating motion
- A swinging motion backwards and forwards.
- E.g. A playground swing.
Examples of motion on a bicycle
- Linear motion: The top of the bike chain moving forward.
- Rotary motion: The wheels turning round.
- Reciprocating motion: The seat being moved up and down.
- Oscillating motion: The handlebars turning or the action of the brake lever being pressed.
