E)change of velocity

Question

Quizplus · Accepted Answer

Acceleration is the rate of change of velocity with time. This means that if an object is changing its speed or direction, it is accelerating. It is not simply the rate of change of position, as an object could be moving at a constant speed but still be accelerating if it is changing direction. It is also not just speed divided by time, as this only gives the average speed and doesn't take into account any changes in velocity. Finally, acceleration can refer to both speeding up or slowing down, as long as there is a change in velocity.
