Fórmula

Speed: v = s / t. Distance: s = v × t. Time: t = s / v. Where v is speed, s is distance, and t is time.

Perguntas Frequentes

What is average speed?
Average speed is total distance traveled divided by total time taken: v = s / t.
What is the difference between speed and velocity?
Speed is a scalar (magnitude only). Velocity is a vector (magnitude and direction). Average speed uses total distance, not displacement.
How do I convert km/h to m/s?
Divide by 3.6. For example, 72 km/h = 72 / 3.6 = 20 m/s.
Can average speed be zero?
Average speed is zero only if no distance is traveled. Even if you return to the start, the total distance is positive.
