Attempting a few trials before the actual experiment can be helpful in order to cause a reduction in this error. Moving on to the experimental relationships, according to the observation analysis and graphical analysis, it was confirmed that the radius and Square of Rotational Frequency had a inverse relation.
Its magnitude is given by the equation: It the two values are close to each other, it could be concluded that the equation for centripetal force is 7 Find out the possible sources of error in this experiment. This error can be improved by measuring the mass of the string used and plugging it in the theoretical formula.
Please re-assemble the Smart Pulley at the end.
The centripetal force apparatus is set up Figure 2. Moving on to the experimental relationships, according to the observation analysis and graphical analysis, it was confirmed that Centripetal Force and Square of Rotational Frequency had a linear relation and were directly proportional.
However the two constants were not exactly the same, after examining the slope of the graph of this part, it was found that the experimental value for k was 0. A certain value on the Newton Spring scale was required on each trial, but however due to irregularities in the path discussed in point Centripetal acceleration lab essay ; the centripetal force values were not perfectly constant throughout the experiment.
This percentage can be used to conclude the efficiency for this part of the experiment. In order to evaluate this relationship, the constant of proportionality of Graph 3 must be determined. Mm of the nylon string.
Record this length in the table below. The accuracy of the experimental results can be improved by the following suggestions: Thus, the string and paper marker may move up and down and the accuracy of the tension T may be affected.
Similarly, even in this lab, there were several systematic errors that caused inaccuracies during the results. The force value showed on the spring scale reflected the mass of the rubber stopper and the mass of the string, however in our observations and analysis, only mass of the stopper was used and mass of the string was assumed zero.
Measure the length of the pendulum from the vertical center of the bob cylinder to the pivot point. When an object is whirled in horizontal circular motion in mid-air with a piece of string as shown in figure 1 abovethe centripetal force on the object is provided by the horizontal component of tension in the string: This error cannot be completely perfected but can be improved.Lab 6: Centripetal Force I.

PYL Centripetal Acceleration The magnitude of centripetal acceleration is given by a centripetal = v 2 /r. Thus at the bottom of the swing, the net force (Tension - Weight) is responsible for the centripetal acceleration.

Lab 6: Centripetal Force I. Introduction The purpose of this experiment was to investigate the motion of an object in a circular path with constant speed. Uniform circular motion is achieved when an object is moving in a circular path.
Centripetal Force Lab Purpose: 1. To study the nature of Centripetal Force 2. To measure the relationship between Centripetal Force, mass, and velocity The force causing the centripetal acceleration, the centripetal force, must obey Newton’s Second Law: Calculate and record the centripetal speed and the centripetal force.
