Questions and Answers

What is the main difference between speed and velocity?

  • Speed includes information about direction, while velocity does not.
  • Velocity is the magnitude of the displacement, while speed is the total distance traveled.
  • Speed is always a scalar quantity, while velocity is always a vector quantity. (correct)
  • Speed is calculated using the displacement, while velocity is calculated using distance.

    • If a person walks 10 meters to point B and then walks back 10 meters to point A, what is the person's total displacement?

  • 0 meters (correct)
  • -10 meters
  • 10 meters
  • 20 meters

    • What happens to speed if a person walks from point A to B and then back to point A in the same time interval?

  • Speed becomes half
  • Speed remains the same
  • Speed doubles (correct)
  • Speed becomes zero
