In formulating his three laws, Newton simplified his treatment of massive bodies by considering them as mathematical points without size or rotation. This allowed him to ignore factors such as friction, air resistance, temperature, material properties, etc. and focus on phenomena that can only be described in terms of mass, length and time. Therefore, the three laws cannot be used to accurately describe the behavior of large, rigid or deformable objects; In many cases, however, they provide corresponding precise approximations. In developing his three laws, Newton simplified objects and reduced them to mathematical points without size or rotation so that he could ignore factors such as friction, air resistance, temperature, and material properties and focus on results that could be fully illustrated in terms of mass. of length and time. Acceleration motion, which is any change in the speed of an object or its direction of motion. For example, circular motion (non-uniform motion) at constant speed is acceleration. This law puts the whole idea in quantitative terms, it says that force is equal to mass multiplied by acceleration, and numbers can be put into that equation. In 1665-1666, the bubonic plague struck England, and this was the time when Newton retired to his family farm following the closure of Cambridge University. The ancient Greek philosopher Aristotle believed that all objects have a natural place in the universe: that heavy objects (such as stones) wanted to rest on earth, and that light objects such as smoke wanted to rest in the sky and the stars wanted to stay in the sky.
He thought that a body was in its natural state when it was at rest, and in order for the body to move in a straight line at a constant speed, an external agent constantly pushed it, otherwise it would stop moving. However, Galileo realized that a force is needed to change the speed of a body, but no force is needed to maintain its speed. Galileo explained that a moving object will continue to move in the absence of a force. (The tendency of objects to resist changes in motion was what Johannes Kepler called inertia.) This idea was refined by Newton, who made it his first law, also known as the “law of inertia”: no force means no acceleration, and therefore the body will maintain its speed. Since Newton`s first law is a reformulation of the law of inertia that Galileo had already described, Newton gave Galileo the appropriate credit. Subsequent generations stood in many ways on the shoulders of the Principia. To give just one example from the 20th century, Emmy Noether created a theorem that describes a very general relationship between conservation laws (such as Newton`s laws of motion) and world symmetries (such as rotational symmetry). Newton`s laws refer to the motion of massive bodies in an inertial frame of reference sometimes called Newton`s frame of reference, although Newton himself never described such a frame of reference. An inertial reference system can be described as a 3-dimensional coordinate system that is stationary or in uniform linear motion, that is, it does not accelerate or rotate. He found that motion in such an inertial frame of reference can be described by three simple laws. The first law of motion is called uniform motion and states that objects move at a constant speed unless they are affected by another force. Newton himself realized that he had not invented any of the laws associated with it.
A French priest, Bullaldius (Boulliau), introduced the correct universal law of attraction (reasoning by strict analogy with light). Galileo found, also after Newton, the first two laws. Wallis, Wren, Huyghens found the third, he adds. The logical relationship between the three laws is unclear. The main law is F = ma, the second law. However, this depends on an undetectable term, the inertial reference frame. This makes all Newtonian mechanics what must be called “local logic”. Newton was the first to fundamentally study motion. He studied and clarified some of Galileo`s ideas and proposed three laws of motion concerning the relationship between force and motion. To explain more about this, imagine a swing between two children who do not weigh the same weight, the heavier the heavier one has to sit closer to this pivot point, and the one who is further away experiences much more movement on the swing.
Newton`s second law of motion states that the acceleration of an object depends on two variables: the net force acting on the object and the mass of the object. The frictional force cannot be eliminated in any object. Even an object like a plane flying in the air encounters air resistance. Therefore, objects do not move continuously if no force acts on the body. Once a body is set in motion, it eventually stops due to the delaying frictional force. However, according to Galileo`s thought, sometimes friction may be absent, in which case a body that is already moving will continue to move indefinitely at a constant speed along a straight line. The second law of motion describes what happens to a massive body when it is affected by an external force. He states: “The force acting on an object is equal to the mass of that object multiplied by its acceleration. This is written in mathematical form as F = ma, where F is the force, m is the mass, and a is the acceleration. The bold letters indicate that force and acceleration are vector quantities, meaning they have both magnitude and direction.
The force can be a single force, or it can be the vector sum of more than one force, which is the net force after all the forces have been combined. The water spills when the state of movement of the container is changed. The water resisted this change in its own state of movement. Water tended to “keep doing what it did.” The container was brought at a high speed to the starting line; The water remained calm and flowed onto the table. The container was stopped near the finish line; The water continued to move and poured onto the front edge of the container. The container was forced to move in a different direction to get around a curve; The water continued to move in the same direction and sway on its edge.
