Editor's Notes
- Matter is anything and everything. Anything you see or is made up of matter and the air that your breathe is made up of matter. Matter exists in all locations on this planet, any other celestial object. That includes moons, planets, stars, asteroids, black holes, quasars and all that good stuff. Matter exists in our minds as the smallest form of a substance. It breaks into molecules, compounds and elements, and its smallest form was considered the atom. The atom has since been broken down into three separate parts; the proton, neutron and electron. These subatomic particles are also considered to be divisible into sub-subatomic particles called quarks. Hypothesis is an educated guess on what you think is going to happen in the end of an experiment. It is the possible outcome of an action or a reaction in effect. When the hypothesis is incorrect, you learn from the mistakes and have a better understanding of “how did that happen?”
- Experimentation is what most scientists do when the want to understand the outcome of a certain action or event. Physicists will experiment with action and reaction and force and work and apply their thoughts to form a hypothesis and possibly discover something they never knew like the answer to “how did that happen?”The outcome or result of an experiment is usually your conclusion of the experiment. It is what you learned from the action or event and what you already knew. Every scientist goes through this process and it is called the scientific method, we all learned this at a very young age and use it constantly without realizing it.
- Mathematics is what helps us understand physics better. We can use words to describe it, but in order to prove and control our experiments and theories we need mathematical equations. There is an equation for force, motion, energy, and even theoretical location. Definition is easy to work with, but for something so complex it is be much easier to let numbers guide us. Mathematics are what engineers use to make sure mechanical objects, like factory machines. They all need their own special mathematical coordinates in order for them to do their job right. We all wonder, “I am never going to use this stupid formula ever again,” when we sit in math class, but low and behold the massive amounts of jobs that are out there all require the knowledge of mathematical physics. Mathematics is what makes the world go round, it is everywhere. Every single aspect of anything can be translated into mathematical terms. There is a number for every force in physics, there is a number for any amount of energy, any distance, or and even theoretical possibilities.
- There are special aspects of physics called laws. They are the truth behind physics, and without them we would absolutely not have the same understanding we do now. Without Sir Isaac Newton, we might have had any concept of gravity or motion. Newton’s laws of motion are the basics to understanding physics. If people can get the meaning of the laws, it would be much easier to apply them to every-day life. Theories are ideas that scientists have come up with using experimental data and patterns from past knowledge. Many theories have been recorded and are true in certain circumstances, but we do not have a way to be sure they are true. This is why we cannot call them laws, because they are not set in stone. There are theories such as “The Big Bang Theory” which describes the origin and beginning of time and the Universe. There are also theories about time travel and space travel. These are far too advanced for scientists to prove or even experiment with.
- Sir Isaac Newton was born 1642, and throughout his early life (his twenties) his work changed the scientific world for ever. When he was young, he wasn’t very consistent with his school work. He tended to not do it and he was unorganized in life, like most geniuses. Newton fulfilled his dream of attending Trinity College of Cambridge where he discovered the tedious works of physicist Aristotle, mathematician Descartes, and other very important scientific figures. During the plagued years of 1665 and 1666, Newton traveled back home because people were not allowed on campus and it was during these years that he mastered their works and discovered his own method of theoretical mathematics. His mathematics professor was unimpressed with Newton’s incentive to study math and science, but when he returned after the plague the professor was overtaken. http://www.clas.ufl.edu/users/ufhatch/pages/01-Courses/current-courses/08sr-newton.htm
- Newton was a slacker. He hardly ever completed his schoolwork, but with his mathematical and studies and physical science studies on his own time truly proved that fact wrong. Newton seemed to study what he wanted to study. After returning to Trinity college after the plagued years, he stepped into his mathematics professor’s position as Lucasian Professor of Mathematics at Cambridge. This was because Newton invented the mathematical process of Infinitesimal Calculus, a theoretical solution process for mathematics. He called it his “method of fluxions”. Newton also discovered new reasoning for theories of light and color, discovered very important factors in the puzzle of planetary motion, and in studying this he pronounced a separate force acting upon us; gravitational force. http://www.clas.ufl.edu/users/ufhatch/pages/01-Courses/current-courses/08sr-newton.htm
- Sir Isaac Newton continued Johannes Kepler’s work on the puzzle of planetary motion. He was unaware of Kepler’s already instated laws of planetary motion when he came to the same conclusions on how the planets revolve around the sun. It wasn’t until later that he learned of the third law of planetary motion when he agreed on its statement. Then came the puzzle of gravity. Newton thought of gravity being caused by centrifugal forces, when an object spins the objects around it are pulled in, however that was not the case. It was in fact the opposite. The is a force of gravity from every object’s center, the earth has a gravitational pull on all objects around it as well as the moon. The moon revolves around the earth due to the earth’s gravitational pull and the earth revolves around the sun due to the suns gravitational pull, as well as every other celestial body in the solar system. It wasn’t until later when Newton addressed the force of gravity, which is how fast objects fall to the ground on earth. Actually, the force of gravity on earth is obscured by the moons gravitational pull on the objects here. It was learned later that the moon causes the tides to change on earth.
- The three laws of motion are mostly related to the mysterious planetary motion, which Newton had discovered himself. Newton discovered the pathway of all the planets in the solar system as they travel in an ellipse, or an oval. The law of inertia describes an object in motion. If something is in still-stand, it still has velocity and acceleration only they are in the form of 0. When in motion, that object will stay in motion at a constant velocity with no acceleration because there is not a separate force acting upon it. In a world without atmosphere and gravity, this law can be observed very easily because all that needs to be done is push an object and watch it go for ever. This is because there is nothing to stop it, there is no force or opposite. The force of a push will cause an object to move, but how fast that object is going and how much that object weighs compared to the gravitational force acting upon it at all times is how we calculate it. Force is equal to the mass of the object times the acceleration of the object. So how much force a velocity provides is calculated by those two numbers. For every action there is an equal and opposite reaction every time. No matter how hard something is pushed, there is still an equal force that pushes back even though it may not look that way. In a world without friction and gravity, this can also be observed. Two objects will be in still-stand next to each other. One will push the other out of the way, but because of no friction that object will not stop. Also, the object that did the pushing will go the opposite way equally as fast because there is no gravity or friction to stop it. http://www.clas.ufl.edu/users/ufhatch/pages/01-Courses/current-courses/08sr-newton.htm
- Johannes Kepler, a German astronomer, is highly responsible for the result of the believed structure of our solar system. He continued the work of early astronomer Nicolaus Copernicus who proposed the reset image of the Universe; that the sun and planets do not all orbit around the earth, the earth, moon and planets orbit around the sun. Kepler continued this study and found this to be true. He studied the orbital path of Mars and discovered that halfway through an earth-year, Mars began to reverse in its orbit. A few more years of observing, Kepler noticed that Mars was going further down a line of orbit each earth-year. This is because mars has a longer orbtial time period than earth and when we finish a year, Mars still has another 2/3’s to go. Kepler also discovered that all the planets orbit around the sun in an elliptical shape, or an oval.
- Force is the energy applied when an object is struck or acted upon. Forces are always in use. On Earth, they are what keep things from going. Friction force, normal force, drag force, tension force, and pushing force.Gravity is the heaviness or force applied by an object or on an object. Gravity is a force applied to all objects from all objects. Any mass has gravity. All people, planets, stars and objects have a gravitational force to them, most of the time it goes unnoticed.
- Motion is the process by which an object changes position over a distance. When force is applied to something, there is always an opposite force acting on it. When a force greater than its opposite is applied on an object, it is set into motion. The object will move until the forces acting on it make it stop.Energy is Power, literally. Energy cannot be created or destroyed, meaning that there is 100% energy in the entire Universe at all times. Period. Energy it provides the ability to do Work. Work is the measurement of the amount of force applied over a distance.
- I am going to apply my research and previously learned information to an every-day living experience. I will provide an explanation to the very common questions such as “how does this work?” or “Why does this happen?” By displaying simple aspects, I mean providing easy explanations such as “for every action there is a reaction” and I will show the audience this simple law. I want the audience to go home after the presentation and do little experiments of their own that have to do with physics. They can drop a ball and see it bounce, and they will understand why after my presentationIf people see how they walk around or even just move things around, they will see basic physics at work. Pushing something requires a force forward and a force from the object being pushed pushes back. When that object slides, it rubs on a surface. That is called friction force, and there is also a drag force caused by the collision of the air on that object. Once people apply this general information, they can learn that physics is always all around them and they can understand that things happen for reasons and not just because.
- While physics can be a very confusing subject, it is still important to our everyday lives as it effects everything we do and help us progress technologically.
- When you walk, you provide a force from your feet to push yourself against the force of gravity. You must apply enough force to overcome your weight force and the gravitational force together. In order to do so, you need energy. The energy you use is provided by the food we eat, and it is converted into chemical energy which you use to make movement and action. You use the energy to create a force while walking to push off the ground, and gravitational energy pushes you back down.When you push on an object, the force you use acts upon that object and a force pushes back. If you try to push something that has more mass than you, it will seem like you are being pushed back. If you are in an area without gravity to keep you in place when you push an object, then the object you push will act on you as well. The object will move away from you, but you will also move away from it. “For every action there is a equal and opposite reaction.” Sir Isaac Newton’s third law of motion. When you slide something across the ground, you must overcome the friction force. Friction is a force opposite of the motion of an object being pulled. If you slide something toward you, the friction force is acting the opposite way. Depending on the weight of the object being pulled, the friction force is a product of the weight and gravitational force. The greater the friction force, the greater the pulling force needs to be in order to slide the object.
- Normal force is a force from a surface. When an object is sitting on a surface, the reason it does not fall through is because the normal force is pushing back on it. This is why we do not fall through the surface of the earth when we walk on it. Normal force is one of the components for calculating friction.First, normal force is calculated simply by taking a force applied onto a surface. That’s all there is to it. A force upon a surface is equal to the normal force. Friction is a very complex force. It is calculated by taking the normal force from a surface and multiplying it by the coefficient of friction, which is determined by the ratio of the net force to the weight force. The coefficient is usually a small number, no more than the value of 2, but using it will describe the friction force for you. Gravitational force is a universal force that is different for every celestial body. Every thing that has mass has a gravitational force. Our planet has a decent amount of force, but it is nothing compared to the force of the sun. The earth has its inhabitants caught in its gravitational pull, that is all of us, and it has the moon revolving around it. However, the sun has the gravitational pull of an exponential value and contains at least 9 known celestial bodies including their satellites and the two known asteroid belts. Even greater than the gravitational force of the sun is the center of our galaxy, the Milky Way, which is believed to be a super massive black hole.
