motion 4Motion is the acceleration, displacement, or velocity (English unit \(ft\), Metric unit \(m\)) 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 fifth called irregular motion which does not actually count as one.


Motion Types

  • Linear motion is anything that moves in a straight line.
  • Oscillating motion (simple harmonic 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.


Brownian Motion

The random movement of particles suspended in liquids or gases caused by the collision of molecules of the surrounding medium.
