Newtons First Law
Newtons first laws states that :
"An object in motion tends to stay in motion
and an object at rest tends to stay and rest
unless acted upon by and outside force."

When in space, Newtons first law is very obvious. When an object in space is set on a course, it stays on that course unless it is acted upon by some outside force. Newtons first law is also present in every day life here on earth. The place where we may experience it the most is in our vehicles. If you are driving your car down the road and you come to a sudden stop, then you are going to go through the widshield unless you are wearing a seatbelt! The reason that you keep moving is because some outside force has stopped your car, but it has not stopped you. This may be a good reason to wear your seatbelt. This concept is also know as inertia.

Newtons Second Law

Newtons second law states that:
"The force exerted on an abject is equal
to the accelertaion multiplied by the mass
of the object on which the force is acting"

Newtons second law can be indentified more easily using the equation F=ma. This is an equation that is very familiar to those of us that wish to do well in any physics class! This equation tells us many things. First it tells us the net force that is being exerted on an object, but it also tells us the acceleration of that object as well as its mass. The force on an object is measured in Newtons (I wonder where they got that from). One Newton is equal to one (kg)(m)/s^2. For example, if superman pushes on a 10,000kg truck and it is moving at a rate of 2m/s^2, then the force that superman is exerting on the truck is 20,000N. For those of us that wish to move on in the field of physics, Newtons second law (F=ma) will forever haunt us!

Newtons Third Law
Newtons third law states that:
"For every action, there is
an equal and opposite reaction."

This law is very interesting. According to this law, when you push against a wall, it also pushes back on you. However odd this may seem, it is very important to us in everyday life. If this law was not true then the force of gravity would pulls us straight to the center of the earth.

Essay on Sir Isaac Newton's Three Laws of Motion

- We have all heard the story of the apple falling on Newton's head while he was sitting against the tree, thus giving him the sudden idea for the Universal Law of Gravity. This, as I am sure most of us know, is not really what happened. A more accurate version would probably be, Newton observed an apple falling from a tree and started contemplating the physics of the apple's fall. The acceleration experienced by the apple, which started at zero when hanging in the tree, then increased as the apple fell....   [tags: physics sir isaac newton laws]

Essay on Newton's Three Laws of Motion

- We experience each of Sir Isaac Newton's laws everyday. In a car, pushing a car, or even in a fight. All of these laws have to do with motion. You can experience the first law in a stopping car, the second when you are a pushing a shopping cart, and the third one in the water. Newton's first law in laymen terms is 'An object in motion tends to stay in motion, and an object at rest tends to stay at rest, unless the object is acted upon by an outside force.' You would feel the law if you were in a fast moving car, lets say 70 mph, which suddenly comes to a stop....   [tags: Physics Motion Newton Science Essays]

Sir Isaac Newton 's Law Of Motion Essay

- Sir Isaac Newton was in my mind one of the greatest people who ever lived. He was born in 1642 and died in 1727. He formulated three laws of motion that help explain some very important principles of physics. Some of Newton 's laws could only be proved under certain conditions actual observations and experiments made sure that they are true. Newton 's laws tell us how objects move by describing the relationship between force and motion. I am going to try to explain his first law in more simple terms....   [tags: Force, Newton's laws of motion]

Newton´s Three Laws of Motion Essay

- Physics is involved in everyday life and can be an essential explanation for how things work. Being a lacrosse goalie involves physics concepts and proves how they apply to every movement that is made on the field. To better understand the physics of a goalie, you must understand how Newton’s Three Laws of Motion work; Inertia, force equals mass times acceleration, and equal and opposite forces, as well as another law torque and leverage. The first law of Newton’s Laws is inertia. The basic definition of inertia is an object in motion will stay in motion until acted on by an outside force, as well as an object as rest will stay at rest until acted on by an outside force (Serwalt,...   [tags: inertia, accelaration, re-action]

Newton’s Laws of Motion in Modern Aircrafts Essay

- The world today requires multiple ways of transport, especially over the Atlantic Ocean. During and before the 1900’s, transatlantic travels were very common and are mainly carried out via boats. However, due to the revolutionary change by the Wright brothers, in 1903, the creation of the propeller planes made shorter travel time between one country to another possible. As technology develops, the transportation of cargo and passengers via airplanes became easier and more efficient with the replacement of jet engines in July 16, 1949, by the famous inventor Frank Whittle (FindtheData, n.d.)....   [tags: Newton’s Laws of Motion]

Isaac Newton 's Principles Of Physics Essay

- Isaac Newton was born on January 4, 1643, in Woolsthorpe, England. He was a smart young man. He went to the University of Cambridge, Trinity College, and The King’s College. Isaac’s professions were as a Philosopher, Astronomer, Physicist, Scientist, and lastly a Mathematician. That’s a smart man , what did I say. He was one of the greatest minds in the 17th century. He made a modern principle of physics. We still use his principles of physics, even if it was published in 1687. He was the only son of a local farmer....   [tags: Newton's laws of motion, Isaac Newton]

The Fundamental Physics of Swimming Essay

- Physics can be applied to every movement, job, sport and task that we perform every day. Perhaps one of the most difficult sports in my opinion is competitive swimming. Swimmers work against many forces as defined later in this paper to move their bodies through the water. The most common swimming techniques and or strokes include the: front crawl, back stroke, breaststroke, butterfly stroke, sidestroke and the dog paddle. Swimming isn’t exactly natural for humans with the exception of being in the womb....   [tags: Newton's laws of motion, hydrodynamics]

The Physics of Car Collisions Essay

- Basic Concepts Issac Newton was the first to state the concepts that are necessary to understanding the physics of collisions. His three laws are used again and again in all the fields of physics: Newton's 1st Law In the absence of external forces, an object at rest remains at rest and an object in motion remains in motion with a constant velocity. This law can be best observed in space, far from the gravity of a star or planet, where there is no friction or air resistance. If, in the middle of deep space, you give a rock a little push, it will continue with the direction and velocity you gave it forever....   [tags: Physics]

The Physics of Bowling Essay

- The Physics of Bowling The definition of physics by some may be the science that deals with matter, energy, motion, and force. Therefore everything in the world uses physics in some way or another. One of the numerous things that deal with physics is bowling. Some of the major parts of physics bowling has is the motions, the ways that Newton’s laws apply, the different momentums, and the energy. Other physics topics include torque, pendulum theory and collisions. In the motion of bowling many things are going on that apply to bowling....   [tags: Physics Bowling Papers]

I think there are enough movies out there to convince you that plummeting to the center of the earth would not be a good thing! What then keeps us from getting pulled down there? It is a force called the normal force, this is the force that pushes up from the ground on our bodies. Now, if it were not for gravity then what would happen? Well we would all go flying off the earth, again, not a good thing! So to review, Newtons third law is what keeps our feet planted on the ground when we are walking around. What a wonderful law.
