Scalar and Vector Quantities

• What do scalar quantities have?

  Magnitude only
• What do vector quantities have?

  Magnitude and direction
• How can vectors be represented visually?

  By an arrow
• What does the length of an arrow represent in vector representation?

  The magnitude of the vector
• What does the direction of an arrow indicate in vector representation?

  The direction of the vector
• What are the key differences between scalar and vector quantities?

  • Scalar quantities:
  • Have magnitude only
  • Examples: mass, temperature, speed
  • Vector quantities:
  • Have magnitude and direction
  • Examples: force, velocity, displacement
