1. The hanging mass from the apparatus was removed by unhooking the spring and the string and the mass was determined to be 1200 grams. The mass was reattached to the string from the top cross arm. 2. The diameter of the center pole was measured using the vernier caliper and it found to be 1.279 cm Using information above, and data in table calculate following: Calculate the angular velocity (ω). Calculate the linear speed of the mass (Vt). Calculate Percent error between the Spring Force and Centripetal Force. Calculate Fc based on the information shown Table Inside distance from center pole to center of radial indicator (cm) 15.2 Time it took to make 50 revolutions (sec) Trial #1 (459g) 30.07 Trial #2 (459g) 28.03 Trial #3 (459g) 29.05 Average (459g) 29.05 Trial #4 (509g) 29.06 Trial #5 (509g) 27.75 Trial #6 (509g) 29.93 Average (509g) 28.91 Trial #7 (559g) 31.59 Trial #8 (559g) 31.59 Trial #9 (559g) 31.88 Average (559g) 31.68

Definition Definition Force on a body along the radial direction. Centripetal force is responsible for the circular motion of a body. The magnitude of centripetal force is given by F C = m v 2 r m = mass of the body in the circular motion v = tangential velocity of the body r = radius of the circular path
