Characteristic
Linear Motion
Random Motion
Direction
Along a straight or curved path with a constant direction
Unpredictable and erratic changes in direction
Path
Predictable, follows a line or curve
Irregular and unpredictable
Cause
Result of forces acting in a specific direction
Usually caused by collisions or random forces
Examples
Car moving along a straight road, ball thrown in a straight line, person walking in a straight path
Movement of gas molecules in the air, motion of particles in a fluid, Brownian motion of particles in a liquid
Equation
s=ut+1/2at2 (Example equation)
Described statistically, often using probability distributions and statistical mechanics concepts
