Lesson 5: Circular Motion

Question 1 • 2003390-Physics 1 Honors Sem. 1 - Peters

In which direction does centripetal force act on an object?

Answer
A
in the opposite direction of the tangential speed of the object
B
in the same direction of the tangential speed of the object
C
toward the outside of the circle in which the object is moving
D
toward the center of the circle in which the object is moving

Explanation

Centripetal force points inward, toward the center of the circular path. This inward force continually changes the direction of the object's velocity, which is tangent to the circle. Therefore, the correct choice is toward the center of the circle in which the object is moving.
