What is the difference between speed and velocity?
What is the difference between speed and velocity?
- Speed has direction while velocity does not.
- Velocity is always positive while speed can be negative.
- Speed is a scalar quantity while velocity is a vector quantity. (correct)
- Speed is calculated as displacement divided by time, while velocity is distance divided by time.
