Question 1 • TX-Physics A

How does an object’s motion change as a result of centripetal acceleration?

Answer
A
The speed decreases in the same direction.
B
The speed increases in the same direction.
C
The direction changes along with the speed.
D
The direction changes but not the speed.

Explanation

Centripetal acceleration points toward the center of a circular path and is perpendicular to the object’s velocity. Because it changes the velocity’s direction rather than its magnitude, the object’s direction changes but its speed does not. The correct choice is D, “The direction changes but not the speed.”
