DYNAMICS -studies the relationship of motion to the forces that causes it. Types of Forces: (a) Normal Force‚ n :When an object rests or pushes on a surface‚ the surface exerts a push on it that is directed perpendicular to the surface. (b) Friction Force‚ f : In addition to the normal force‚ a surface may exert a frictional force on a object‚ directed parallel to the surface and opposite the motion or impending motion of the object. f s = µ s n - static friction‚ maximum friction before the object

Laws of Motion and Thermodynamics The first example is oscillating a pendulum‚ which is categorized in the law of motion due to the object remaining in that state unless an external force is applied. The second example stating cooling food and drinks in a refrigerator is categorized in the laws of Thermodynamics due to thermalization. The third example of using the coffeemaker can be a combination of both laws due to moving touching to coffeemaker to make create an action is Law of Motion‚ however

Controlled variables: 1. The lighting was kept constant during the complete test. No additional light sources were added throughout the experiment‚ nor were any light sources removed throughout the experiment. This minimized the errors involved with trying to read and record the indicated measurements on the ticker tape‚ as well as the ability to analyze the experiment. 2. The same person measured and recorded the height and length of the incline plane and level horizontal track to ensure consistency

Motion of the Cars In this part of the experiment‚ we are trying to figure out how fast each of the cars are moving using our own measurements. We are also asked to make a mathematical equation that describes the motion. What we plan to do is use 2 meter long meter stick to measure the distance of the cars and record the position at each time interval. After that an average velocity can be found. After we used the average velocity‚ we were able to put it into the equation of a line formula and

In Chapters 1 and 2 of “Full Planet‚ Empty Plates”‚ Lester Brown argues that the world population is increasing and food is becoming more scarce. I agree with both of Brown’s arguments because the increasing world population correlates with the growing scarcity of food. Chapter 1 discusses the rise in food prices and scarcity of food. While food is becoming more expensive and scarce‚ people are becoming more hungry. As people cultivate more land‚ the soil becomes depleted‚ and is then harder to

For my visual I did a stop motion animation explaining how Edmond Dantès evolves and changes throughout the story. Dantès started to evolve and change when he was sent to the Châtaeu D’If‚ so I started my video by describing what Dantès was like before he was sent to prison. For the video‚ I used both words and pictures to show how Dantès changes throughout the story. The beginning of the video started out with the quote‚ “He was a tall‚ slender young man‚ no more than twenty years old‚ with dark

Kepler’s Laws of Planetary Motion Johannes Kepler is a well renowned scientist‚ who is well known for his discovery of the laws that define the movement of the planets in the universe. With well defined studied and researches‚ Kepler has defined three main laws defining the planetary motion. These laws give a clear overview of the way things move around and are used by the engineers for the development of all related equipment‚ devices and even the study of the planets. We would hence discuss these

Case Study: YouTube‚ the Internet‚ and the Future of Movies Question 1 The movie industry was face with competitive forces that made the industry unattractive. The threat of substitutes was extremely high. This was because the increased levels of high speed Internet made downloading easier and faster‚ which made pirating movies easier. This increased the threat of substitutes because consumers were no longer buying movies‚ the consumers started to download movies and television shows free of

In her painting‚ Plate with Wreath‚ Robin Jebavy uses everyday objects and combines them with unordinary colors as an attempt to make people change how they think about their everyday life. Jebavy herself states that her artwork is “a reference to our fragile and often precarious human condition.” The manner in which she uses color allows for the objects‚ such as plates and glasses‚ to be unrecognizable at first glance. She does this to blur the sense of reality and illusion that all people have
