Question 7 • TX-Physics A

An object is in circular motion. How will the object behave if the centripetal force is removed?

Answer
A
It would move in a line away from the circle’s center.
B
It would move in a line toward the circle’s center.
C
It would move in a curved, circular path.
D
It would move in a line tangent to the circular path.

Explanation

Centripetal force continually changes the direction of an object’s velocity, keeping it on a circular path. If that force is removed, the object continues in the direction it was moving at that instant, which is tangent to the circle. Therefore, it moves in a straight line tangent to the circular path.
