This lab experiment was to confirm and see how the Work, the Mass ,the Velocity, the Acceleration and the Energy of an object are related to each other and what will happen if they vary.
For accomplish the task at hand we were given a box of masses( these masses were .02Kg each)
We then set up the a pulley using Lego-Robot such as:
In the program, “http://web.cas.suffolk.edu/faculty/lshatz/Sustainability_class/Labview/Lab2_2.vi“. We first entered a constant Force and keeping changing the Mass and observed how the acceleration reacts to it.
In the second part, the Mass was kept constant and the Force was changed and the results observed.
There were two was of recording the Data, The first one was to record directly the values from the program after each experiment or to open an excel file were the program automatically saves the values measured. We had to be careful because the excel file is not updated if it is open during the experiment.
End end result was:
As a conclusion we can say that, when finding the Work done by an object the Force ( mass and acceleration) is very important. If the force is kept constant and the mass is increase or decrease the acceleration respectively decrease or increase. And if the mass is kept constant and the power is increased or decreased, the acceleration respectively increase or decrease. These three element are related by the formula: Force= Mass * Acceleration.
