# The Three Concepts Of Sir Isaac Newton's Laws Of Motion

1301 Words 6 Pages
Introduction

In 1686, in the book, Principia Mathematica Philosophiae Naturalis, Sir Isaac Newton penned his three laws of motion. In the first law he states that, “Every body perseveres in its state of rest… unless it is compelled to change that state by forces impressed thereon.” (p. 83) His second law builds upon this principle, “The alteration of motion is ever proportional to the motive forces impressed.” (p. 83) Newton’s third law, perhaps the most famous, serves to tie the three concepts together, “To every object there is always an opposed and equal reaction: or the mutual actions of two bodies upon each other are always equal, and directed to two contrary parts.” (p. 83) Three hundred and thirty years later, Newton’s laws continue
From the ball kicked by the soccer player, to packages shipped globally, even to space shuttles that orbit celestial beings. Newton’s Laws allow us to understand the nuances of motion and ultimately manipulate how objects behave in a state of unrest. In Adrian Cho’s article, Drop Test, scientists prepare to drop two cylinders in outer space to prove Galileo’s notion of the equivalence principle, explained by Newton’s Second Law, force equals mass times acceleration. “Although Galileo’s analysis jibes with the equivalence principle, he wouldn’t have understood it that way… Newton proved that the two types of mass were equal by showing that different materials swing at the same rate.” (Cho 2015, p. 1097) This is only one of the many ways in which scientists continue to use Newton’s Laws of Motion. Airbags were created on Newton’s Third Law that, “every action is an interaction.” (Zimba 2009, p. 283) When someone is involved in a car accident, an airbag ensures that the person is not hit with the full force of his or her body hitting the windshield. Instead, the body in motion is de-accelerated as it crashes into the airbag. This slowing down of motion helps to cushion the person’s impact and ultimately save lives. This phenomenon also explains why companies package their products the way they do, using materials such as styrofoam and bubble wrap to cushion impacts while the package is shipped. In the next section, I interview a packaging engineer and learn how she uses Newton’s Laws of Motion to ensure that products reach their destination in good

• ## Isaac Newton's Laws Of Motion And Crumple Zones

Isaac Newton’s Laws of Motion and Crumple Zones Crumple Zones design and function The crumple zone is the front and the rear of a motor vehicle that is designed to crumple without difficulty and to absorb the force of the impact in a crash. Crumple zones are also known as crush zones and they absorb energy in a crash so that it doesn’t transmit to the occupants as much. The zones are now made in cars to prevent death for occupants or serious injuries when in a crash. The front of the vehicle works as a cushion to slow down time so that the vehicle can stop completely and that less forced is applied to the occupants. It reduces injuries and deaths around the world.…

• ## Albert Einstein: Time Dilation

Time Dilation is the effect of the Einstein’s theory of relativity. It is for making the ticking of clock on the space stations than those on the normal one in the Earth. It is the difference of an elapsed time between two particular events that are precisely measured by the observers. If you try to launch yourself off the Earth with a high speed and pulled a U-turn, you will return to the Earth in future. People on Earth would experience faster time than you that traveled with your rocket.…

• ## How To Prevent Car Maintenance Essay

As a car owner, preventive maintenance of you car is probably your most important responsiblity to keep your ride safe and happy. It can save your money on repairs arises in future. The preventive maintenence of your car carry out with checking tire pressure and fluids, changing the engine oil, perform scheduled inspection, check your bettery, replace the air filter and windshiled wiper as well as checking other parts of the car. It can helps you to keep your car helathy and catch the serious problem before it becomes a major problem. Here are some of the basic reasons that define why the preventive maintenance of your car is important.…

• ## Drinking And Driving: The Dangers Of Drunk Driving

In the book Drunk Driving it says these devices analyze (bac) blood alcohol content and can prevent a vehicle from starting if the driver has consumed even a tiny amount of alcohol. Also these devices are good because it keeps them off the roads and keeps them out of harm 's way. I asked my one of my family members how is it to have this device installed in your truck he said “it sucks but it is good because it keeps me from driving drunk and from getting a ticket and going to jail.” Also the driver must breathe into the device before starting the vehicle and again while driving whenever the machine asks. Also in the book it said Judges in many states require drivers to install interlocks as part of their sentences, but (MADD) Mothers Against Drunk Driving wants it to be mandatory nationwide for even first-time offenders.” I agree with Madd because it will make these drunks think twice about what they did and it will keep them from driving drunk. Also critics say that “the interlocks are in accurate, easily fooled, and may be dangerous.” I disagree with this because i asked my family member again how accurate are these devices?…

No matter what stain or whatever it is that is damaged in the inside the detailer will do their very best to take that out to make it look brand new. Having your car clean it will not be so embarrassing to take out your car. By cleaning it it will prevent from rust to form on your car from all the salts or what ever gets on the car it will take off the things so it won't rust. Washing your car frequently can prevent the buildup of these particles and keep its parts and paint finish longer. This also prevents costly repairs and improves your vehicle’s performance.Keeping your car clean also saves you a lot of money.…

• ## Gravitation-Movement: Sir Isaac Newton's Theory Of Motion

This had profound philosophical and scientific consequences. The unification into what became the laws of gravitation became a symbol of the predictive and quantitative power of science. The fact that a single law could explain the motion of a cannonball and the motion of Mars revolutionized our understanding of our place in the universe. In the centuries after Newton, scientists and mathematicians created powerful techniques and concepts for understanding complex phenomena such as tides and perturbations. In 1915 Albert Einstein published a new theory of gravitation (The General Theory of Relativity) that conceived of gravitational effects as caused by curvature in a four-dimensional space-time surface.…

• ## Sir Isaac Newton And Newton's First Law Of Gravity

Gravitational theory is a theory that states any two particles attract each other with a force that is equal to the product of the two masses. Before Newton, the views on gravity and the motion of the planets, were quite different. Aristotle believed the universe never had a beginning and would never end; he believed it was eternal. Kepler’s view on gravity and motion was that the planets orbited around the sun and orbits faster the closer it becomes to the sun. Galileo believed if something started at the same speed, the speed will stay constant.…

• ## Vostok 1's Impact On Space Exploration Development

It meant that people could survive in space and there was a possibility of making more discoveries. When the Soviets were able to the beat the US to a common goal when they were so close to accomplishing it themselves it logically lead to some tension and made the US more focussed on completing the next step in space history. When President Kennedy announced that the US would reach the moon before the Soviets it showed that the US wanted to win the Space Race and that they were going to do anything to redeem themselves after not being able to get the first person in space. Ultimately Vostok 1 made the US want to have a larger breakthrough than the Soviets. This lead to the start of the Apollo Program.…

• ## Galileo Galilei: The Start Of The Scientific Revolution

Galileo created huge changes in the seventeenth century. Firstly, Galileo created the law of inertia, which was that when an object is in motion, it keeps on motion until it is stopped by a force. Galileo's most prized invention was the advancement of the telescope. The advancement of the telescope confirmed Copernicus' theory on the heliocentric view of the universe. Through the use of his telescope, he was also able to look at the moon, observe a supernova, verify the phases of Venus, discover sunspots, and discovered that the moons and the planets were not perfectly round.…
