Complete the sentences to describe the difference between speed and velocity. Speed describes how fast an object moves. Speed is described by and time. Velocity is speed with . Velocity is described by and time.

a) Distance

b) Direction

c) Displacement

Explanation:

Speed is the distance covered in per unit time by an object or person. It is how fast an item is moving. speed does not have a direction. It is the ratio of distance covered and time taken.

Example: A car covered 100 km in 1 hour.

Its speed will be 200 km/h.

On the other hand, velocity has direction as well as magnitude in it so it is a vector quantity. Velocity is the ratio of displacement and time.

Example: A car moved 100 km in 1 hour southwards.

Its velocity will be 100 km/h (towards south).

Thus, the correct answer is :

a) Distance

b) Direction

c) Displacement
