What is the difference between speed and velocity?

Back

Speed is a scalar quantity (magnitude only), while velocity is a vector quantity (magnitude and direction).

If a cyclist increases their speed from 10 m/s to 15 m/s, what is the acceleration if it takes 2 seconds?

Back

Acceleration = (Final Speed - Initial Speed) / Time = (15 m/s - 10 m/s) / 2 s = 2.5 m/s².
