Question

Which statement describes the difference between speed and velocity

a. Velocity is speed with a direction.B.Velocity is speed divided by time.C.Velocity is speed multiplied by time.D.Velocity is measured in meters per second while speed is measured in meters.

Answer 1

Velocity is speed plus a direction.


30 miles per hour to the north
30 miles per hour to the east

These are the same speed but different velocities.

Answer 2

Explanation :

Distance : The total path covered during the entire journey of any particle.

Displacement : The smallest path covered by a particle.

Speed : It is defined as the total distance covered divided by total time taken. It has only magnitude not direction.

Velocity : It is defined as the total displacement traveled by a particle divided by total time taken. It is a vector quantity. It has both magnitude and direction.

Hence, the correct option is (A) " Velocity is speed with a direction".
