Day 3 Group 23

A) What changes did you have to do to your original design and why?
So far, we have made various changes to our design, where our project does not even looks very different compared to our blueprints. We have used the basic format of our design, but specific parts like ramps, change into using parts like tubes. We have still incorporated most of the toys that have been drawn on the design. Furthermore, the pulley on our design is still a go, as we only need to build it and make it work. Since we have not really approached the end of our project, we still have not determined whether our initial idea of how the ball will be launched will be used.

B) What other challenges have you faced up to this point?
Our group has faced various challenged recently. First off, our room only has one workable powerful and everyone wants to use it. The tube, in which the ball will be initially dropped, is not at sharp enough angle to keep the ball moving; henceforth, adjustments will have to be made. Fed and I have been coming up with various ideas on how to make the pulley system work, which has also proved tp be quite difficult. Yet, overall, just the general building of the project is very tedious.

C) Outside of simple machines and energy transfers, discuss two other physics concepts in detail that are demonstrated in your project.    
One of the concepts we are using would be Newton's First Law, that states any object will in rest unless acted upon by an outside source. For the ball to move we are relying on its momentum  to carry it on the more flatter planes. Another concept of physics would be friction. Even though the ball is being push down by gravity to make it move, due to friction, the ball loses a lot of energy and slows down. We need friction so that the marble can slow down before it drops so it won't go overboard.
