✌️✨⛄Hope its helpful ✨⛄✌️

Explanation:

Acceleration: It is a measure of the change in the velocity of an object per unit time. Acceleration can be caused either by change in direction of motion or change in speed or both.

Answer 2

Answer:

Acceleration, rate at which velocity changes with time, in terms of both speed and direction. A point or an object moving in a straight line is accelerated if it speeds up or slows down. Motion on a circle is accelerated even if the speed is constant, because the direction is continually changing.
