EXPERIMENT 7
Centripetal Force

Physics 186 lab

OBJECTIVE
The aim of this experiment was to describe how the magnitude of centripetal force for consistent circular motion may be determined development a centripetal force apparatus with variable hie rotor.
Procedure
For this experiment, we needed to obtain the following set of measurements to calculate our information:
Average rotational frequency (f=N/60)
As we change magnitude the rotations per minute on the centripetal force apparatus we hold open the pointer modernize. This was done on five different trials, averaged, and thence divided by 60 routines.
Suspended mass
Measurement was interpreted by putting weights to the spring (via weight hanger) produce the very(prenominal) extension of the spring as when on the rotor (pointer aimed at the index screw position), noting when the pointer will cause it to rise and point toward the index screw
Cylinder Mass
This was stamped on the cylinder.
Total hang mass
Mass of the suspended mass and the cylinder mass. M = M1 + m
Radius of the circular path
Using a Vernier caliper, we mensurable the distance between the axis of rotation (the index screw) and concentre mass of the cylinder.
Data
Data Tables 5 and 6 (attached sheets)
Once we take a shit collected our data, we were able to calculate the Total suspended mass, the get up measure of Fc, Computed Fc, and the percent passing.
Error
Based on my calculations the percent difference that resulted may pass on been due to not understanding the performance of the variable speed apparatus rotor causing us to initially take the first rpm reading of the pointer moving and not allowing it to reset. This is seen with difference between the first and second trials. Other possibilities I feel that I may have contributed to a high percent difference was that I did not converted units properly or simply mathematical.
Conclusion
This experiment allowed us to understand the magnitude...If you want to get a full essay, raise it on our website: Orderessay
