In this lab, our purpose is to determine the relationship between the mass and period for an inertial balance. We are determining an equation to connect the mass and period for an inertial balance.
Lab Setup:
Here we used a clamp to hold the inertial balance to the table. We place the photogate at the other end of the inertial balance to record the period.
Here we use tape to safely secure weight to the end near the photogate. We then pull the balance to create a period which the photo gate will record.
Description:
In this lab, we are recording the period of the inertial balance when it is empty and when weights are slowly added on. To do so, we must find the average period with no additional weights, then add 100g and find the average period. We repeat this until we reach 800g. With the equation we come up with, we will be able to determine the mass of our unknown by simply using our average period. The photogate is connected to our LabPro which is connected to our Macs.
Data Table:
Our Mtray range is between 320g-350g. With these values, we were able to get 0.9997 for our correlation. We plotted a period vs mass and it was a linear graph.
This is our calculations. To find the mass of the unknown. We used Ln(T)=n*ln(Mtray + m) + lnA.
Summary:
We came up with an equation that is very precise. We developed an equation with our obtain period values and known mass.
