Question 1: If an object moves in a circle with constant speed, then
Answer: b. We can label that force(s) "centripetal"
Question 2: If the speed of an object in Uniform Circular Motion doubles, the force required to keep in moving in a circle with the same radius
Answer: c. Centipetal force depends on the square of speed
Question 3: "Gravity can act as a centripetal force". True or False?
Answer: True. If an object moves in a circle oriented vertically, gravity pulls it towards the center of the circle during the upper portion of its motion.
