Scaler and Vector Quantities

• What are scalar quantities?


  Scalar quantities have magnitude only and no direction.
• Can you give examples of scalar quantities?


  Examples include mass, temperature, speed, energy, distance, and time.
• Why is distance considered a scalar quantity?


  Because it has magnitude but no direction.
• If you travel a distance of 800 meters, what does that tell you about your journey?


  It tells you how far you have traveled but not the direction.
• What is the difference between distance and displacement?


  Distance is a scalar quantity, while displacement is a vector quantity that includes direction.
• What is an example of a vector quantity?


  Displacement is an example of a vector quantity.
• How is displacement defined?


  Displacement is the distance traveled in a specific direction.
• If you travel 800 meters but your displacement is 500 meters due west, what does this indicate?

  This indicates that you traveled a longer distance than the straight-line distance to your endpoint.
• How can vectors be represented visually?


  Vectors can be represented by arrows, where the length indicates magnitude and the direction indicates direction.
• What are some examples of vector quantities?


  Examples include displacement, weight, force, velocity, acceleration, and momentum.
• What are the key characteristics of scalar and vector quantities?


  • Scalar quantities:
  • Have magnitude only
  • Examples: mass, temperature, speed, energy, distance, time
  • Vector quantities:
  • Have both magnitude and direction
  • Examples: displacement, weight, force, velocity, acceleration, momentum
• How do you represent a vector quantity on a map?


  • Use an arrow:
  • Length represents magnitude
  • Direction indicates the direction of the vector
