To simplify our discussion, we will first consider the case of a particle on
a circular path or orbit. Later we will remove the constraint of the circular
4.2 Uniform circular motion
When we watch a child riding a horse on a merry-go-round such as the ones
shown in Fig. 4.5, we know that the motion of the child is circular, meaning
that the distance between the child and the fixed center of the carousel never
changes. if the motion is stable, not at the beginning or the end of the ride,
it is also nearly uniform, referring to the speed of the child not changing.
But we know for sure that the velocity of the child, at least its direction,
is constantly changing, because every moment we look at the situation, the
child is moving in a different direction. This is sketched in Fig. 4.6(a). Can
we figure out how the velocity changes, provided that the speed is constant,
that is, v1 = v2 = v and the distance between the child and the carousel
center remains constant, too?
First we can qualitatively…
are used to generate the circular motion, and this circular motion is converted into a linear motion by connecting extension blocks to the wheel.
Now, I am going to pick a 70 extension block and connecting it to the wheel block like this, and I close it with a circlip. In the same way, I created another wheel block, and now, keep them aside.
Let me Pick a 70 extension block and connect it with a 50 ext block like this, and I am going to attach another 70 extension block to it, then, I…

President Andrew Jackson barred the proposed bill re-chartering the Second Bank of United States in July 1832. He disputed that the bill, in the form with which it had been presented to him, was totally incompatible with sound policy and justice as well as the constitution. In the veto message, the President argued that the Bank’s license was completely unfair by virtue of the fact that it gave the bank extensive, almost monopolistic power in the market particularly in the…
“Life is very mysterious and there are many things we don’t know. And there are elements of magic realism in every culture, everywhere. It’s just accepting that we don’t know everything and everything is possible” by Isabel Allende. Relevantly, magic realism was practiced in Latin America, it goes beyond reality to express impossible ideas. During the mid-1900s, an Argentinian author, Jorge Luis Borges, wrote the short story “The Circular Ruins”, this story illustrates the dreams of light and…
Greatness is only rewarded to those who seek it, not to those who wait for it to be handed out. Accordingly, producing movies based on great works of literature means translating the original work into something that not only has a great moral, but that is also visually captivating throughout the entire duration of the film. Beowulf the poem was published by an anonymous author in the 900’s and reflects the Anglo-Saxon civilization which had just recently converted to Christianity at the time of…

society creates a monster on both the two sides.
A series of jump cuts constitute to the convolution of the first scene. The introduction of the movie conveys a skewed perception, foreshadowing the violence that might occur later in the movie. The first scene of the movie elaborates the idea of random editing. This is demonstrated when a stranger asks Mallory’s name. After a certain rude remark, Mickey is ready for action. Before the violence begins, a quick cut to dark is shown. The horror…
The advancements that “The Curious Case of Benjamin Button” made great strides in improving motion capture technology. Although I do not believe that the final product turned out to be very good, the techniques that were developed made other ambitious films a possibility. Specifically, the technique used to capture the subtle nuances of an actor’s performance, which was later used to great effect in the film “The Pirates of the Caribbean: Dead Man’s Chest”, in regards to the creation and…
