This week has been really fun to work with the Pendulum. I have learned a very important thing during this assignment i.e. Thinking about the flow and level of energy throughout the motion of any object. There are definitely some forces acting upon objects (Internal OR/Either External) making objects to move in a certain way, It's difficult at times to figure that out, but i think it ain't impossible, the best way to learn all this is observation ofcourse :D And also Use your brain its all simple physics :P that we actually notice and watch in our day to day life. Any ways, i hope i made sense to what i said and if i didn't ignore to what i said just use your brains :P
Here's the final version of the assignment.
