5. Distance is a
quantity, it has magnitude but no direction.

same.
12. It is defined as the rate of change in velocity.
13. It refers to the total change in velocity divided by the total time taken for
the change.
14. It is the opposite of acceleration where the velocity of an object
Decreases.
15. It is the total distance travelled divided by the total time of travel.​
