Force and Energy, Velocity and Accretion, and Power
This lab was very simple but a majority had technical problems. Our group, Jean and I were able to do this lab without any problems. We made all of the graphs and got our data accurately as possible. The first thing we did was download the program which records data received to an excel file. The first step was to explore newton’s law F=ma. I found that the acceleration increases as the mass decreases or if mass increases acceleration decreases. I also found that the acceleration increased as power level increases. We then graphed this data in excel.

This is the excel file that shows we found our own data and made graphs to show that our data was accurate.
The second part was to explore conservation of energy. We had to compute potential energy using PE = mgh (mass)*(gravity)*(height). This was found using data that was recorded. We then had to make a scatter graph to find the battery drainage compared to mass which is shown in the third graph. The last graph we made was power used. This was calculated by PE/t. Potential energy divided by time. The last graph shows energy vs energy used.
I think this could be used in sustainability energy because we can see how much the battery is discharged. These are not the most efficient machines and run off rechargeable batteries. I also learned that if mass is higher than the potential energy of an object is higher. With this lab I learned how to use excel spread sheets and how the robot can relate to energy used.
