Answer:
a) Distance
b) Direction
c) Displacement
Step-by-step 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
