Newtons Laws
Newton’s I, II, & III Law

Newton’s three laws of motion explain everything that happens to objects in Earth. Anything from kicking a ball to a human being walking is explained by Newton’s three laws of motion. They explain something different of the motion of an object, put together they explain everything. In order they are; Newton’s First Law: The law of inertia; Newton’s Second Law: The law with the concept of acceleration; Newton’s Third Law: The Law of Action & Reaction.

Newton’s 1st law states that any object at rest will remain at rest or if its moving it will remain moving at a constant speed until force is has acted upon it or is exerted on it. For example, a ball will remain at rest until a force acts upon it. Yet, it will keep going at a constant speed unless another force overpowers it. When a force is applied it doesn’t necessarily have to be one force, it can be multiple. Those forces could include gravity, friction, and your own. In order for this law to be applied to an object, it must be in equilibrium. An object is only equilibrium if the vector sum of all forces equals zero. With these forces & objects also experience acceleration explaining the connection with the two laws.

In addition, Newton’s Second Law states that forces acting upon an object go through acceleration. Acceleration is a change in velocity or speed. For example, a ball going down on an inclined plane will go through certain acceleration. It will usually keep gaining speed during each time interval. However, an object will not accelerate forever, the faster an object goes the less it acceleration it has. When its acceleration reaches zero it has reached its terminal velocity. Generally, the heavier an object is the harder it is to get it to accelerate. The bigger the mass, the more force is required to accelerate. Also, an object’s acceleration could be affected by friction and air drag. Air drag applies to all objects even if it’s in free fall or not, making it go through the previous two laws. Acceleration modifies inertia, yet friction affects acceleration. It being like a cycle the objects general process goes through Newton’s Third Law of Motion: The Law of Action & Reaction. Furthermore, Newton’s third law states that whenever a force is exerted on an object the object will also exert an equal opposite force back. For example, when you punch a wall it hurts your knuckles as much as it hurts the wall. The stronger or softer you hit the wall, the stronger or softer it will hurt you. This law of motion states that you can’t touch without being touched. In other words everything you do towards another object will do the same back. In some cases, the consequences are different. For Instance, a bug is flying down the road and a car’s windshield squishes it. The car hit the bug as well as the bug hit back whereas the car had more mass overpowering the bug’s mass making the bug lose the “battle”.

In conclusion, with Newton’s First law I learned that an object will remain at rest or if in motion will remain at motion. In order for an object to move or stop a force needs to act upon it. This is where Newton’s Second law comes in. With that force it causes the object to accelerate or decelerate making it move or stop moving from the original velocity. Then friction comes to the equation making it impossible to accelerate infinitely. With friction an object reaches a terminal velocity proving that for every action there is a reaction. The object accelerates yet stops accelerating at terminal velocity it being the reaction. This proves why Newton’s three simple laws explain everything that happens to an object in Earth. Also, it explains why they go together. Each one overpowers one another yet its impossible for one to act without the others.

Newton’s First Law of Motion explains that objects in a state of uniform motion tends to remain in rest unless an external force is applied to it. Galileo’s concept of inertia is termed “Law of Inertia”. Law of Inertia, an object in motion will continue in the same motion unless acted by an outside force. Aircraft in flight is an example of First Law of Motion, four forces on an aircraft; lift, weight, thrust, and a drag. Consider the motion of an aircraft at constant altitude, we can neglect the lift and weight, a cruising aircraft at constant speed and the thrust balances the drag of the aircraft. This is the first part sited in Newton’s First Law; there is no net force on the airplane and it travels at a constant velocity in a straight line.…

Isaac Newton’s first law of motion states that an object in motion tends to stay in motion, and an object at rest tends to stay at rest, unless an outside force is acting upon the object. This is a simple, yet complex concept that we see and feel every day. Long before this law of motion was observed and put into words it was acting upon us as human beings, as well as every other object, not only here on earth but everywhere in the universe. How Newton’s first law of motion affects things in space is just as important as how it affects us here on earth.…

First let’s get to know some history about the man behind all of this, Sir Isaac Newton. Sir Isaac Newton, the man who is responsible for what we all have come to know as the “Laws of Motion” was born on January 4, 1643, which is very often displayed as December 25, 1642, if using the older version of the Julien calendar, in the Helmet of Woolsthorpe, England. Sir Isaac Newton is believed to be one of the most influential scientists known to have ever lived. His ideas became the basis for the physics we all know and use today, well some of us. He not only studied optics, astronomy, and math, he even ended up creating what we all know as “calculus”(Mathematics). Sir Isaac Newton was a mathematician and physics scholar who transformed…

These laws helped others create several inventions and expanded the world's view on mechanics. For example, many amusement park rides began from Newton's laws of motion, roller coasters and Ferris wheels. One law states that an object in motion will say in that motion, unless acted on by an external force. For example, a roller coaster is made with hills so that the motion of the roller coaster won't be stopped by friction till the ride is over. Another law states that an object's acceleration is determined on the amount of force and the mass of the object. For example, if a person kicked a brick wall, it wouldn't move, but if the person kicked a balloon, it would move. Another example of the law is inside an engine; when the gasoline explodes in the cylinder of an engine, the force of the explosion forces the piston to move, which projects the machine in a direction. The final law of motion states that every action has an equal and opposite reaction. For example, a bird flies because it's wings push the air down, forcing the bird up into the air. An example of an invention for this law is the invention of rockets. A rocket is projected forward by an engine, while pushing the flames and exhaust backwards. These laws also helped English inventors create new inventions: the first internal combustion engine, the first electrical generator, the linear motor, the hydraulic crane, the…

First, Growing up Newton had a difficult life. He was born as a premature baby. He also had to grow up without his dad because his dad passed away three months before he was born. When Newton was three his mom left him to go live with her new husband, leaving him to live with his grandparents. Newton has many influences on today’s life. One of his many influences on us today is the Three Laws Of Motion. The idea of the Three Laws Of Motion states that anything at rest will stay at rest unless an outside force affects it.…

Newton’s laws of motion can be applied to any moving or resting object. For example, the movement of motor vehicles are explained by physics. The law of inertia states that an object at rest will stay at rest and an object in motion will stay in motion unless or until acted upon by a force. This can explain why when people don’t buckle their seatbelts, they are propelled out of the car, even though the car stopped moving. Newton’s second law of motion states that force is the product of mass times acceleration. Therefore, a heavier vehicle will fare better in a collision than a smaller lighter…

If we lived in a frictionless world (or in space), it would be easier to see Newton's First Law of Motion applied. Objects would always follow the Law of Inertia and resist change in their motion. But on earth we experience external forces like friction and gravity. Therefore, objects do not always keep in their rest state or continue moving at constant velocity, and in the real world the law does not hold perfectly true.…

Newton’s first law was an object in motion will continue moving unless something stops it from moving. That law relates to my project by saying my contraption will stay in motion till it hit the ground. Newton’s second law was heavier the object the more force it takes to move and lighter objects require less force too move. The force in which the egg hits the ground will equal the mass of the egg. Newton’s third law is for every action of force there is an equal and opposite reaction of force. While moving downwards, the force of gravity is pulling the egg down. However, when the force is acting on the opposite direction too that’s due to air resistance.…

In order to understand motion, one needs to look no further the Sir Issac Newton. Newton's studies eventually led to the development of three distinct, but related theories dealing with velocity, acceleration, inertia, friction and momentum, these theories are so widely accepted that they are commonly called "Newton's Three Laws of Motion." These laws, after almost three hundred years of testing and scrutiny, remain as fundamental principles governing the world we live in. By increasing our understanding of…

Isaac Newton was born on Christmas day in 1642, in Lincolnshire, England. Newton attended Trinity College in 1661 and had both his Bachelor of Arts and his Master of Arts by 1669. That same year he became the associate of the French Academy of Sciences. He was elected to Parilment, then appointed a warden, and finally, President of the Royal Society. Newton was a master of science and mathematics. He discovered calculus, before Leibniz' became popular. Perhaps Newton's most popular discovery, though, was gravity. As the story goes, Sir Isaac Newton was resting under a tree one day in his garden, when an apple fell from it and hit him on the head. Thus, he discovered gravity. The earth's gravitational pull pulls objects toward it. However, many people believe that this is only a myth created to simply illustrate Newton's discovery. <br><br>Along with Newton's many discoveries, the three laws of motion are famous. These include inertia, acceleration, and the idea that for every action, there is an equal and opposite reaction. Inertia is the idea that a body in motion will remain in motion, and a body at rest will remain at rest. For example, if I were to throw a baseball into the air, it would keep going until grasvity pulled it back down to earth. However, if I left it sitting on a table, it would lie there until some kind of force were to move it. If I were to push a skateboard across the floor with all of my might, the skateboard would accelerate more than if I gave it a light shove, simply because there was more force behind it. More force = more acceleration. If I were sitting on a swing and someone were to grab hold of the swing, pull it backwards, and release, I would move forward in the opposite direction. This demonstrates the idea that, for every action, there is an equal and opposite…
