• What are scalar quantities?

  Scalar quantities have magnitude only and no direction.
• What is an example of a scalar quantity?

  Distance is an example of a scalar quantity.
• Why does distance not provide information about direction?

  Because distance is a scalar quantity that only has magnitude.
• If you travel a distance of 800 meters, what does that tell you?

  It tells you how far you have traveled, but not the direction.
• What is the definition of magnitude?

  Magnitude refers to the size of a quantity.
• What are some examples of vector quantities?

  Displacement, weight, force, velocity, acceleration, and momentum are vector quantities.
• How does displacement differ from distance?

  Displacement is distance 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 does the length of an arrow in a vector representation signify?

  The length of the arrow represents the magnitude of the vector.
• What does the direction of an arrow in a vector representation signify?

  The direction of the arrow represents the direction of the vector.
• 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 calculate displacement from distance?

  • Displacement = Distance in a specific direction
  • Example: If distance is 800 meters, and direction is due west, then displacement is 500 meters due west.
• How are scalar and vector quantities used in physics?

  • Scalar quantities are used for measurements that do not require direction.
  • Vector quantities are essential for understanding forces and motion, as they include direction.
