scalar and vector quantities

• • vector quantities have a magnitude and direction
  • examples of vector quantities are:
  • force
  • velocity
  • displacement
  • acceleration
  • momentum
• • vector quantities are represented by an arrow
  • the length of the arrow represents the magnitude
  • the direction of the arrow represents the direction of the vector quantity
• • scalar quantities have only magnitude
  • examples of scalar quantities are:
  • speed
  • distance
  • mass
  • temperature
  • time
