Acceleration is a vector quantity that is defined as the rate at which an object changes its velocity. An object is accelerating if it is changing its velocity. Sports announcers will occasionally say that a person is accelerating if he/she is moving fast. Yet acceleration has nothing to do with going fast.
Acceleration is a change in the speed of an object (contrary to popular belief-acceleration ban be an increase or decrease in speed). Velocity of an object only changes whe â¦ n acted on by an external force like a push, friction or other force. Objects in motion stay in motion until acted on by an external force.hen velocity changes, that means that the object either moves faster, or moves slower, or moves in a different direction. Any of these changes is called acceleration. A â¦ force is necessary to cause it.
