    First, the air track was adjusted until it was horizontal to the table surface. Then a pulley system was set up: a glider with a flag was placed on the air track; it was connected to a hanger with an inextensible string. The airflow was also adjusted such that the glider moves freely with no friction. A photo-gate was also placed onto the air track, and this was connected to the computer program, LoggerPro. When the experimental…

    Y-Component x- X-Component Mathematical Model Basic Equations: Force Equation (used to find the force of any given object): F=ma F-Net Force, m-mass, a-acceleration Summation of Forces on X-Axis: 〖ΣF〗^x=F^(G,x)-F^Sp 〖ΣF〗^x is the sum of the forces on the x-axis, denoted by the superscript x, and the x-axis follows the Free-Body Diagram above. F^(G,x) is the x-component of the Force of Gravity by the Earth on the cart. F^Sp is the Force of Spring on the cart. Hooke’s Law for Springs:…

    For this plan I was given the challenge of finding a way to help the actors remember the order of the play and their entrance and exits. I wanted to push the actors to use the space and not have to use language to communicate. The challenge here was to create a plan that would be sustaining and challenging but not restricting to the Deaf actors by taking their language away from them. The intention of the workshop was to slowly over stimulate the actors so that they would start to multitask. By…

    used. There are four forces acts on a train. One of them is its weight which balanced by the typical reaction of the tracks. The third one is the thrust force produced by the locomotives which move the train forward, and the fourth one is the combination of air resistance and the rolling friction between wheels and the railway tracks. There is another force called Centrifugal force act on a train when it takes turns. This force tends the train to run straight, but this force is overcome by the…

    assumed to exist in the sticking and sliding regions, respectively[42]. Most analyses have applied classical friction situation following Coulomb’s laws which is based on coefficient of friction [e.g., [55], [62]]. Frictional sliding force F is proportional to the force N normal to the interface at which sliding is taking place. This model can be expressed by: However, the above equation fails to give accurate prediction in high normal stress conditions. Several studies applied modified Coulomb…

    When society breaks down, death and destruction incur. In the book The Lord Of The Flies by William Golding the effects of the breakdown of society is a major theme. Humans identities are formed when society’s rules and laws are non existent, and humans are forced to rely off of their own morals. This can be seen when Ralph’s tribe is demolished by Jack because of Jack 's different ideology . In addition, Piggy’s logic and intelligence when talking about advanced topics on the island also show…

    Fireworks or gunfire? It may be difficult for some non-gun-wheedling citizens to tell the difference, but every cop knows ringing of gunfire. Miraculous patient recoveries are everyday norms for doctors, well, at least on TV. Several aspects of TV don’t depict real-life scenarios that happen in these job fields, instead they show the exciting, romanticized, alluring and often skewed, concepts of the job. Cops don’t experience shoot outs every day, half their day or sometimes more is spent on…

    say the least, “Motion is the actuality of what potentially is.” (Kosman, 1969, p. 40) Although Aristotle thought long and hard specifically about planetary motion, he never answered the question of whether celestial bodies moved, and if so, by what force. Abu ‘Ali Ibn Sina, a Muslim scholar in 1000 AD, confirmed Aristotle’s suspicions by saying, “Nobody begins to move or comes to rest of itself.” (Hecht, 2015, p. 80) Almost seven hundred years later Newton will state this fact in his First Law,…

    necessarily mean that there is no force acting on it. Motion can also be studied by using momentum (f=((mv-mu))/t ) as a quantity. Uniform motion is when the displacement of an object is constant with respect to time. Note that there has to be some displacement for it…

    Within The Character of Physical Law, Dr. Feynman details the characteristics of nature. He describes nature as being incredibly complex, pointing to examples such as the orbits of the planets around the sun and tidal movement. Yet, he is able to describe nature as being simple. For a potential reader this can be confusing, as something cannot simultaneously be simple and complex. It is through the understanding and the application of logic that Feynman connects simple ideas to larger and more…
