Circular and Satellite Motion - Mission CG2 Detailed Help

An object moves in a circle at a constant speed. The direction of the acceleration vector is best described as being ____.


 
Uniform Circular Motion and Acceleration:
Accelerating objects are changing their velocity - either the magnitude or the direction of the velocity. Objects moving in a circle at a constant speed are accelerating due to their changing direction. The direction of the acceleration is directed toward the center of the circle about which the object moves. Such a direction is described as being centripetal.
