What is true about the forces in circular motion situations?

What is true about the forces in circular motion situations?



a. There are no forces.

b. The net force is parallel to the motion.

c. The net force is perpendicular to the motion.

d. The net force is opposite the motion.



10 points to correct answerWhat is true about the forces in circular motion situations?c. The net force is perpendicular to the motion.What is true about the forces in circular motion situations?The acceleration is proportional and parallel to the force. So, in any type of motion, what is true about the acceleration is also true about the force. The only difference is mass, as explained by Newton's II law f = m * aWhat is true about the forces in circular motion situations?The force due to uniform circular motion is F = mv/r^2, and the force vector always points toward the center, perpendicular to the motion (c).
