r of the best answer. 1. All are true of centripetal force EXCEPT 6. It's directed toward the inside of a circle. B. It keeps an object going in a circle. C. If an object goes in a circle, it creates centripetal force. D. It's the net force of an object moving in a circle. 2. The positive direction of torque is A. found by using your left hand B. clockwise (c.w.) counter-clock wise (c.c.w.) dependent on the direction of force 3. Two bugs are on a rotating CD. Bug A is 10 em from the center, and Bug B is 20 cm from the center. The rotational speed of A is B. A. faster than C. the same as B slower than D. None of these 4. If the sun suddenly disappears (i.e. goes away), the planets would A. keep going in their orbits (circular path) as they are now. B fly off in a straight line, tangential (perpendicular) to their orbit. C. spiral or fly inward toward where the sun was. D. fly off in the opposite direction of where the sun was. 5. Two bugs are on a rotating CD. Bug A is 10 cm from the center, and Bug B is 20 cm from the center The linear velocity of A is _B. A. slower than C. the same as B. faster than D. None of these. 6. If the linear velocity of an object doubles,, its centripetal acceleration will A. increase by 2x C. decrease B increase by 4x D. None of these 2 7. Which of the following is NOT a unit of rotational speed? A. 60 RPM / 2n Hertz / 21 B. Meters per second D. Radians / second 8. A car can stay on the road in a curve at constant speed because A. inertia keeps the car in the turn. . a force pulls the car outward. B. friction pulls the car inward. D. the engine pulls the car forward. 9. All are examples of rotation EXCEPT C. the Earth going around the sun each yr A. an ice skater spinning B. the Earth spinning on its axis each day D. Two of these
