• What is a scalar quantity?

  • a quantity that only has a magnitude
  • a quantity that isn’t direction dependent
• what is a vector quantity?

  a quantity that has both a magnitude and an associated direction.
• how can a vector quantity be drawn and what does it show?

  • as an arrow
  • the length of the arrow represents the magnitude
  • the arrow points in the associated direction
• give three examples of vector quantities

  • velocity
  • displacement
  • force
