• Scalar quantities


  Physical quantities that only have a magnitude but no direction
• Magnitude


  Size, can be measured with a numerical value
• Scalar quantities

  • Speed
  • Distance
  • Mass
  • Temperature
  • Time
• Vector quantities


  Physical quantities that have both a magnitude and a direction
• Vector quantities

  • Velocity
  • Displacement
  • Acceleration
  • Force
  • Momentum
• Representing vectors

  1. Use arrows

  2. Length of arrow indicates magnitude

  3. Direction arrow is pointing indicates direction
