Answer:
Change of velocity means that the moving object is accelerating or deaccelerating and it is given by the formula: a=(v2-v1)/(t2-t1) a stands for acceleration, v1 and v2 for change in speed and t1 and t2 for the change in time.
Step-by-step explanation:
n object can change velocity in a number of ways: it can slow down, it can speed up, or it can change direction. A change in speed, or a change in direction, or a change in both speed and direction means that the object has a change in velocity.
