(20 points) what is true about the forces in circular motion situations? a. the net force is opposite the motion. b. the net force is parallel to the motion. c. the net force is perpendicular to the motion. d. there are no forces. i'm pretty sure the answer is b. "parallel to the motion" but i thought i'd double check because this test is open book. explain your answer as well : )
