Estimate the expected % uncertainties in each of these three kinds of measurements considering the apparatus you have used and the range of values you had. Give objective reasons for your estimates. 35 To find Fc, you multiply 4 π 2 by the weight and the radius divided by the average of T. since the only factors that change are weight and T, they should equal the same number since T is dependent on the weight and should parallel each other. When m increases, so should T. because the radiuses are the same and only multiplied by gravity, Fstatic should stay the same in Table B.
Experiment 7 (5) Question #1: Explain, using algebra , why both values of F in Table B should theoretically be equal while this is not true for the values of F in Table A. (6) Question #2: To find F c by Formula (1) you had to measure: (i) masses. (ii) distances. (iii) time-intervals. Estimate the expected % uncertainties in each of these three kinds of measurements considering the apparatus you have used and the range of values you had. Give objective reasons for your estimates. 36
Experiment 7 Conclusion: In conclusion we were able to study and understand how uniform circular motion works and that an object that is in uniform circular motion moves in a circle at a constant speed by a force. We were also able to study and understand how centripetal force works through the use of the centripetal force apparatus. 37
