What Is Speed?
Speed is the distance an object travels per unit of time. When considered together with direction, it becomes a vector quantity and shows how fast motion occurs.
How is it calculated?
How Is Speed Calculated?
v = distance ÷ time
- Enter the distance traveled and the time elapsed.
- Divide the distance by the time.
For example, 100 m in 20 s: 100 ÷ 20 = 5 m/s.
