What is the main difference between speed and velocity?
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.
