What is the definition of displacement?
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?
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
