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.
Newton’s Law the first law being an object at rest tends to stay at rest and an object in motion tends to stay in motion with the same speed and in the same direction. In this movie I would say that Newtons 3rd Law came into effect. That being for every action there is an equal and opposite reaction which states for every force there is an equal and opposite force.
Bottle rockets are great models to examine Newton’s three laws of motion. The bottle rocket will remain on the ground until an unbalanced force, water, thrusts the rocket upward. This is defined by Newton’s first law of motion: an object at rest stays at rest or an object in motion, stays in motion (in the same direction/at the same speed) unless acted upon by an unbalanced force. It is also known as the law of inertia.
First law- Objects at rest will stay at rest and objects in motion will stay in motion in a straight line unless acted upon by an unbalanced force.
In 1687, Newton published Philosophiae Naturalis Principia Mathematica (also known as Principia). The Principia was the “climax of Newton's professional life” (“Sir Isaac Newton”, 370). This book contains not only information on gravity, but Newton’s Three Laws of Motion. The First Law states that an object in constant motion will remain in motion unless an outside force is applied. The Second Law states that an object accelerates when a force is applied to a mass and greater force is needed to accelerate an object with a larger mass. The Third Law states that for every action there is an opposite and equal reaction. These laws were fundamental in explaining the elliptical orbits of planets, moons, and comets. They were also used to calculate
Issac Newton said in his 2nd law : 'The rate of change of momentum of
The three laws of motion are three rules that explain the motion of an object. The first law is the law of inertia. It states that every object remains at rest unless it is compelled by an external force. The second law is the law of acceleration. This law shows when there is a change in force, it causes a change in velocity. Finally, the third law states that every force in nature has an equal and opposite reaction. His discovery in calculus help confirms his second law of motion. Calculus also gave Isaac Newton powerful ways to solve mathematical problems. Lastly, for the color spectrum, he produced a beam of light from a tiny hole in a window shade. He placed a glass prism in front of the beam of light creating a color spectrum. In Newton’s undergraduate days, Newton was greatly influenced by the Hermetic tradition. After learning about the Hermetic tradition it influenced him to look at a different perspective into his discoveries and theories. One of the myths that followed the discovery is his discovery of universal gravitation. It is said that while Isaac Newton was thinking about the forces of nature, an apple fell on his head and he found the theory of gravity. There is no evidence that an apple fell on Newton’s head, but the evidence is shown that Newton got an idea of the theory of gravity when he saw an apple fall from a tree. During his life; however, Isaac Newton faced many obstacles. When he published some of his ideas in Philosophical Transaction of the Royal Society, some people challenged his ideas such as Robert Hooke and Christiaan Huygens to a point where Newton stopped publishing his work. During his life, he also suffered a nervous breakdown in a period of his life. He was convinced his friends were conspiring against him, and he couldn’t sleep at all for five

Newton’s 2nd Law of Motion states that acceleration is directly proportional to net force when mass is constant. This experiment dealing with variable forces has as its objective the verification of this law. In this experiment this law is tested for verification in straight forward way. Through the use of a Force Sensor and an Accelerometer, data collection of observations and measurements that a force exerts on a small cart along with the cart’s accelerations are to be determined. The sensors’ measurements will be employed to give meaningful relationships between the net force on the cart, its mass, and its acceleration under these conditions. The resultant measurements revealed will verify and determine the force and acceleration relationship as stated by Newton.
What is there to know about the three laws of motion? The three laws of motion are only one of the countless things formulated or developed by the astounding seventeenth century physicist and mathematician, Sir Isaac Newton. Sir Isaac Newton is considered one of the pioneers for the ever growing world of physics. Newton was the metaphorical outline for numerous brilliant physicists such as Albert Einstein, Niels Bohr, Richard Feynman, and Erwin Schrödinger. Many of those names may be much more familiar than that of Isaac Newton, but in the science world, Newton is a beloved figure since a vast number of rules and theories were derived from him. Newton’s rules and theories still hold true today, just like with his three laws of motion. One of Newtons many clever quotes or sayings is, “Tact is the art of making a point without making an enemy.” Because Newton lived by this saying his entire life, he was a successful physicist who is still important in todays world. Even though Newton was a powerful mind in the science world, he was also an astute mathematician, making breakthroughs in the mathematical world as well.
The gravitational force at the surface of the planet is the force that binds all bodies to earth, this force is one of the four forces recognized by physicists, and this kind of force is known as "gravity" it attracts every celestial object to earth, and though it is the most important of the forces essential for our lives, it is the least comprehended of them all Throughout ages scientists have tried to solve the mystery of gravity, and one of the first discoveries concerning gravity was made by Aristotle who concluded from his experiments that the downward movement of any body is that has weight had a proportional relationship between its quickness in motion and its size. However this theory was accepted for centuries, but after a series of experiments made by Galileo, Aristotle's theory was proved to be incorrect, as Galileo said after a series of experimenting at the Pisa tower that bodies of different sizes fall with the same speed. Later on, the idea that the force is needed so as to change the motion of the body was discovered. After that a great scientist was to improve all the previously accepted theories, this scientist was Newton who was to make decisive advances in understanding gravity. In his first law Newton said that a body in state of rest or uniform motion in a straight line will keep on moving unless acted upon by a force, while in his second Newton expressed his first law in a more quantitative way as he said that force acting on a body is the rate of change of it's momentum which can be put in a rule as F= ma Where (F) is the force acting on the body while (a) and (m) are the acceleration and inertial mass of the body respectively. Newton also made the law of gravitation in which he expressed the gravitational force of attraction between any two bodies acting along the line joining them as Where (m) is the mass of the two bodies and (r) is the distance between them, while (G) is the proportionality constant known as the constant of gravitation, afterwards Newton made his very important assumption in which he showed that the inertial mass of a body is identical to its gravitational mass which implied that the gravitational force exerted on or by an object is directly proportional to its inertia.
F = ma : where F is force; m is the mass of the body; and a is the acceleration due to that particular force
The acceleration of a body or object is directly proportional to the net force acting on the body or object and is inversely
The acceleration of a body or object is directly proportional to the net force acting on the body or object and is inversely proportional to its mass. (F=ma)(Newman)
The third law is, “For every action there is an equal and opposite force.” This means that there is a reaction force equal in size, but in opposite direction. So when an object pushes another object it gets pushed back in the opposite direction.
In the natural world, physicists find new discoveries constantly. Some of these discoveries include the study of motion and forces. The well-known scientist, Isaac Newton, came up with the three laws of motion, which state rules and facts about the movement of an object. Our textbook states the laws of motion, as ?A body in motion will remain in motion at a constant speed and direction unless an outside force acts upon it. The net force acting upon an object is directly related to the mass and acceleration of the object resulting acceleration is in the direction of the net force, which is the vector sum of all forces acting upon the object. Finally, the third law of motion states that when one object applies a force to another, the other object applies the same amount of force back to the first object, but in opposite directions.? With these laws of motion, we can understand in detail how our world works. Also, that the movement of an object is more complex than a simple push. This discovery is taught to students all over the world because of its great importance and will continue to enhance the knowledge of the mystery of our earth.
