Lab 5 Pre-Quiz 1. Draw a free-body diagram for the swinging stopper pre-lab investigation in the centripetal acceleration lab. 2. What do you think is meant by force-interpolated? 3. Describe how the photogate gives linear velocity in this experiment, now that the motion is circular rather than linear. 4. Make a prediction for the relationship of centripetal acceleration and velocity. 5. Make a prediction for the relationship of centripetal force and velocity.
