PRE-LAB CIRCULAR UNIFORM MOTION 1. Verify the dimensional correctness of Equation 2 by using the units of speed and distance to show that a, has acceleration units. 2. Which of the following statements best describes the net force acting on an object moving with uniform circular motion? Circle your choice(s). a. The net force acting on the object is away from the center of the motion and the acceleration of the object is toward the center of the motion. b. Both the net force acting on the object and the acceleration of the object are away from the center of the motion. c. The net force acting on the object is tangent to the circle in which the object is moving and the acceleration of the object is toward the center of this circle. d. Both the net force acting on the object and the acceleration of the object are toward the center of the circle in which the object is moving. e. The net force acting on the object is toward the center of the circle in which the object is moving and the acceleration of the object is tangent to the circle in which the object is moving. ac 22 T Equation 2 3. A bob of mass 0.449 kg is moving in a circular path of radius 0.180 m at a constant speed. If the period of the motion is 0.770 s, find the speed of the bob 4. Find the magnitude of the centripetal acceleration of the bob in QUESTION 3. 5. Find the magnitude of the centripetal force acting on the bob in QUESTION 3. 6. What part of the apparatus shown in Figure 6.3 (see ACTIVITY 1) provides the centripetal force acting on the bob? If the magnitude of the centripetal force acting on the bob is to remain constant, what property of the part of the apparatus you've identified must also remain constant?
