PHYSICS PRACTICE TEST: INCLINED PLANES, HOOKE’S LAW, CIRCULAR MOTION 1. An object moves in a clockwise direction along the circular path as shown in the diagram at the right. Three points along the path are labeled - A, B and C. For each location, draw a straight-line vector arrow in the direction of the velocity vector; label this vector as v . Then draw a straight-line vector arrow in the direction of the acceleration vector; label this vector as a . 2. When the roller coaster car is at the bottom of the loop, the direction of the acceleration and the net force is directed _____________ (up, down). When the roller coaster car is at the top of the loop, the direction of the acceleration and the net force is directed _____________ (up, down). 3. In order for the conditions described in question #6 above to be true, how does the magnitude of the normal force compare to the magnitude of the gravity force at the two locations. Put a greater than (>) or a less than (<) symbol in the blanks below. Loop Bottom: Fnorm _____ Fgrav Loop Top: Fnorm _____ Fgrav
