Question

multiple choice question
how is the direction of the centripetal acceleration of an object in circular motion related to the direction of the velocity of the object?
perpendicular
at a 45° angle
opposite
parallel

Explanation:

In circular motion, velocity is tangent to the circular path. Centripetal acceleration is directed towards the center of the circle. A tangent to a circle and a radius (direction of centripetal acceleration) are perpendicular.

Answer:

perpendicular
