When I was a child I was obsessed with miniature wooden and paper airplanes, I was always gluing Popsicle sticks and clothes pins together or making my mother mad by using all the printer paper on new airplane designs. The thing that fascinated me was that I could never fully grasp what made them glide in the air the way that they do but never fly. In my mind the small plane should have flown better than a 100,000 lb. metal object. It wasn’t until I was older and had my first physical science class that I really started to get a grasp on what was really going on to make something that large liftoff and continue to fly. There are two names that stand out when speaking about the physics of flight: Sir Isaac Newton and Daniel Bernoulli. Without them there would be far less understanding of the forces of flight and the physics behind the art of flying.
Sir Issac Newton was a mathematician and physicist who transformed the scientific world in 1666 with the development of the theories of gravitation at the young age of 23. Twenty years later in 1686, Newton published Principia Mathematics Philosophiae Naturalis, Latin for “Mathematical Principles of Natural Philosophy”, which detailed his work in mathematical physics and presented his three laws of motion. His first law is commonly known as the law of Inertia, and it states “A body in motion at a constant speed will remain in motion at that speed unless acted upon by outside force; A body at rest will remain at rest unless acted upon by...

...Uses of Fluid Mechanics with Relevant References. Fluid mechanics is the application of the laws of fore and motion to fluids. Within fluid mechanics there are two studies of fluid mechanics: Fluid statics, the study if fluids at rest within a system, or Fluid Dynamics which is the study of fluids that are in motion within a system. A fluid is a substance that has no fixed shape and yields easily to external pressure. The substance continually deforms or flows under an applied shear stress. Fluids are a subset of the states of matter and include three of the four states of matter [1]. An example of tangential shear stress can be something as simple as a piece of wood floating on a small body of water. If the force, F, is applied at the end of one side, then the board transmits a tangential shear stress, denoted as, t, to the surface of the water. Shear stress is defined as the tangential to the area over which it acts, and is expressed in the same units as Direct Stress [2]. “If a shear stress is applied to the surface of a solid, the solid will deform a little, and then remain at rest (in its distorted shape). One can say that the solid (at rest) is able to resist the shear stress.” [2] Both the board and the water will move as long as the force exerted and the tangential sheer stress are not equal to zero. Think about this, a fluid can only experience a normal stress when there is no force being acted upon the system obtained by the fluid. Therefore, since the fluid is at...

...evidences with reference my experiences in the past. "No two gardens are the same. No two days are the same in one garden"- is a famous quote by the writer Hugh Johnson [Thomas, 1985, p115]. This quote is applicable for human beings too. No two individuals express the same opinion and thought. As their thoughts vary, their idea on perceiving things vary. A research work eventually results in an inference by a person on a particular concept. Obviously, no two researchers conclude the same thing. All of us would be aware of the Big Bang Theory. I am also not an exception to it. I am also one of the poor victims who were made to sit in a class room with boring lectures and lessons. Big Bang theory was the one that I studied in my higher secondary Physics class in a chapter by name, "Universe". The Big Bang theory as all of us know is one of the widely accepted theories that explain about the origin of our universe. According to Big Bang theory, the universe has emerged out of nothing [Karen C. Fox, 2002]. The Big Bang theory has proven that there is an origin...

...Answers to Conceptual Integrated Science End-of-Chapter Questions Chapter 1: About Science Answers to Chapter 1 Review Questions 1 The era of modern science in the 16th century was launched when Galileo Galilei revived the Copernican view of the heliocentric universe, using experiments to study nature’s behavior. 2 In Conceptual Integrated Science, we believe that focusing on math too early is a poor substitute forconcepts. 3 We mean that it must be capable of being proved wrong. 4 Nonscientific hypotheses may be perfectly reasonable; they are nonscientific only because they are not falsifiable—there is no test for possible wrongness. 5 Galileo showed the falseness of Aristotle’s claim with a single experiment—dropping heavy and lightobjects from the Leaning Tower of Pisa. 6 A scientific fact is something that competent observers can observe and agree to be true; a hypothesis is an explanation or answer that is capable of being proved wrong; a law is a hypothesis that has been tested over and over and not contradicted; a theory is a synthesis of facts and well-tested hypotheses. 7 In everyday speech, a theory is the same as a hypothesis—a statement that hasn’t been tested. 8 Theories grow stronger and more precise as they evolve to include new information. 9 The term supernatural literally means “above nature.” Science works within nature, not above it. 10 They rely on subjective personal experience and do not lead to testable hypotheses. They lie outside...

The equation will be dimensionally correct except sometimes in cases when the right hand side of the equation has more than one term. c. The equation will not be dimensionally correct. d. All constants of proportionality will be correct. C3. How long has it been that scientists have accepted that the nucleus of the atom consists of neutrons and protons? Think of your answers in terms of order of magnitude. a. about a decade b. about a century c. about a thousand years d. since Aristotle C4. Consider the sine of any angle between 30° and 40°.
