How does an object’s motion change as a result of centripetal acceleration? the speed decreases in the same direction. the speed increases in the same direction. the direction changes along with the speed. the direction changes but not the speed.

When we look at centripetal acceleration, the acceleration is a change in velocity. Since velocity is a vector, when we change direction, we have an acceleration even if the speed is not changing. An object's motion changes direction but does not change in speed when looking at centripetal acceleration.

Answertraveling around a circular trackexplanation"traveling around a circular track" is the best answer as you could be traveling around a circular track at a constant speed. your velocity would therefore have the same magnitude but will always be constantly direction. since acceleration is the rate of change of velocity, the rate of change will only involve the direction of velocity and not the magnitude.wrong choices: "an object at rest" does not accelerate at all"increasing speed while traveling around a curve" means that the acceleration will not be constant due to only change in direction; it will be constant due to both magnitude and direction"an object in free fall" does not necessarily change direction
