Here is our final lab: https://www.youtube.com/watch?v=_w5GLvRXEwE
Most energy is lost as Eliza letting the marble slide down. As the marble slides down, its potential energy is being converted into kinetic energy. The total energy is always conserved. I will pick the first energy change, which is potential energy to kinetic energy, to perform my calculation. In order to know how much energy changes during this section, first I need to know at what height the marble is rolling down. Height and the mass of the marble are also taken into consideration. For this, I will determine the final energy at the end of the first energy change. The change in kinetic energy indicates the work of the marble. Its power can be calculated using its force and velocity; the product of these two components will give me the power of the marble. Total energy is very much simple since it is either the initial potential energy or the final kinetic energy.
This lab is a good experience for me as I learn a lot through it. Working with other students sometimes pisses me off, but as we comes together and agree on our ideas it is pretty easy to overcome the task. This assignment gives me a good knowledge of what I would be doing in college. I hope we can have few more of this the rest of the year.
