Motion

Motion 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  -  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  -  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.
