Aim

The purpose of this kind of experiment is always to determine the relationships among radiuses, mass, velocity and centripetal power of a rotating body. We all used logger pro to accurately measure the orbital length of the content spinning mass and used these kinds of measurements to look for the interrelated connections of the specific properties and viewed the results graphically.

Data and Calculations

The black markings on the string are about 10 cm apart in length, measured from your center in the spinning mass. Part A: Factors that influence Spherical Motion

Speed versuse Centripetal Force

Submit the stand holding the Spinning mass (M) plus the radius (R) constant.

What can you conclude about the relationship between the acceleration and the centripetal force? A graph can be very helpful right here to see virtually any trends.

Persons can usually identify a thready relationship, we don't typically think regarding quadratic associations. For that reason, we all usually make an effort to plot charts in such a way that the graph ought to appear thready. This may indicate changing the shape of whatever we are plotting from let us say v to a huge selection of. From your data table, would it be more likely that a straight-line graph will be attained by plotting Fcent against versus or v2? Plot both on the same graph and go over their implications. Using the table above, we need to plot the centripetal force versus the speed and the centripetal force versus the velocity-squared.

The graph of Force versus Velocity-squared creates the most thready result.

By simply analyzing both the graphs previously mentioned, we can see that as velocity increases, thus does the centripetal force. Which means that velocity and force are directly related. This is further more reinforced by the equation of centripetal force:

Notice that if we plot Push on the y-axis and v-squared on the x-axis, this is effectively a straight collection:

The variance inside the data is most likely due to a variable...
