CHEMISTRY IN OUR DAILY LIVES Chemistry In Everyday Life Chemistry in everyday life : Our entire universe is made up of matter which is constantly changing forms and evolving into other forms of energy. Chemistry is defined as the study or science of this ever changing matter. The other sciences which we study commonly like biology‚ physics and mathematics are all dependent on chemistry and are only specific studies under the elaborate subject of chemistry. Chemistry is also seen in biological

Physics 2 Application to IT and daily living! Thermal Physics Thermal physics the study of temperature‚ heat‚ and how they affect matter. I can apply this in determining how hot or cold the object. Though I have my senses in concluding the temperature of an object‚ they are unreliable and often misleading. Ex. A metal and a stone that is both expose to sun. I can conclude; base on what I’d learned that the metal is hotter than the stone. Putting a metal spoon in a cooking soup. To make

exist. Car manufacturers study it carefully to determine how quickly a car will spin out of control. Here‚ a higher moment is created such that the car is less likely to lose control in a spin. Many sports also use the concept‚ as in the example of the skater. Divers use this so they can use the lowest moment of inertia and fastest spin to move seamlessly and enter the water. The same goes for baseball players and golfers so that they can move have a very effective swing and hit the ball at the correct

Use of Paralanguage and Kinesics in Everyday Life The use of kinesics and paralanguage in everyday life is the most prominent use of persuasion we use subconsciously. They are used subconsciously because you may not know what they mean. Which can cause cultural tension if you do something that may seem harmless to you but may be a great insult to another culture. Paralanguage has many forms such as whistling which can be used by many people as a means of entertaining by whistling a song or

people actually realize the physics that are involved in almost everything that they see or do. While there are multiple ways that physics is used in a soccer game‚ this paper explores three parts and the physics that are involved in each one. The three parts that are going to be discussed are passing‚ heading‚ and throw-ins. These three can explain how physics can work from a soccer ball coming or going in each and every direction. Also‚ every part that is discussed uses different parts of the body

Newton’s 2nd law of motion by using an Air-track. The air-track can make the trolley frictionless by testing the velocity with different weights and shows that F=ma. Research question: How much acceleration does the frictionless trolley has? Aim: Use the air track to measure the acceleration of the no friction trolley by hanging with different mass of weights. Apparatus: * 1 air track * Weights (40g‚ 50g‚ 60g‚ 70g‚ 80g‚ 90g‚ 100g) * 1 string (bigger than 200cm) (plastic) * 1

population is a challenge‚ which is compounded by increased pressure on natural resources such as land‚ water and fossil sources of raw materials. There are many advantages and disadvantage on using fossil fuel as our primary energy source. Our technology use to harness the energy is well developed because of the decades long we have used fossil fuels for energy. Fossil fuels are the cheapest and reliable of all source energy. They are the best energy fuel than wind and solar‚ which are unreliable. Consequences

How to Excel in Your Physics Course Most students realize that putting off studying until the day before the exam and then cramming at the last minute is not efficient. Some students do this anyway‚ because so far they have gotten away with it. Perhaps most of the other students you previously competed with had poor study skills. This may have allowed you to adopt poor or non-existent study habits and still keep up‚ or even get good grades if you are naturally a better student. Now that you

ballet dancers you think of grace and beauty. While you watch a dancer dance you never think of the physics and mathematics behind their every move. Physics is described as a thing that is all about measurement‚ and that if you know the units of measurement that physics uses and how they work you will understand everything else you’ll learn about (Dennis and Moring 1). The textbook definition of physics is “the study of matter and energy and their relationships” (Zitzewitz 1). Ballet cannot be defined
