Can a car be accelerating when its speed is constant?
A. Yes. Velocity has both a magnitude (speed) and a direction. If the direction is changing there is an acceleration. B. No. If speed is constant there is no change so therefore no acceleration. C. No. Acceleration is the rate of change of velocity. If the speed is constant the velocity is not changing. D. Yes. Acceleration and speed are not related, so a constant speed has no effect on acceleration. © 2019 McGraw-Hill Education
