Questions and Answers

What is the definition of displacement?

  • The length of the path an object travels divided by the total elapsed time
  • The difference between speed and velocity
  • The change in position of an object, including both magnitude and direction (correct)
  • The coordinate of the object’s initial position

    • What is the main difference between speed and velocity?

  • Speed is a scalar quantity, while velocity is a vector quantity (correct)
  • Speed is the displacement of an object, while velocity is the change in position
  • Speed is a vector quantity, while velocity is a scalar quantity
  • Speed has both magnitude and direction, while velocity only has magnitude

    • What is the graphical interpretation of velocity?

  • The area under the velocity-time graph (correct)
  • The distance traveled by an object
  • The coordinate of the object’s initial position
  • The length of the path an object travels divided by the total elapsed time
