The Brainliest Answer!

*VELOCITY----velocity is the distance travelled in a straight direction upon time...............*

*ACCELERATION------------Acceleration of a body is defined as the rate of change of its velocity with time. i.e Acceleration = Change in velocity / Time taken for change..............*

*VELOCITY RATIO------------Velocity ratio is the ratio of distance covered by effort to the distance covered by load.*
