One day Isaac Newton studied under an apple tree and an apple on his head. Newton wondered why apples fall. These questions yield answers that famous, namely because of the gravitational force that pulls everything to the Earth. The underlying story of the birth aitulah Newton's laws in this world.
The answer was poured into a book entitled "Philosophiae Naturalis Principia Mathematica". The book was considered the greatest scientific works of all time. In the book also described the three principles that are now known as Newton's laws. Newton's laws of physics followed by all scientists as Einstein until a fix.
Isaac Newton's greatest work is not actually the discovery of gravity or Newton's law itself, but the calculus. Newton was the foundations of mathematics called calculus. Calculus is a tool for understanding Newton's laws. Calculus is also an invaluable tool in developing the science of geometry, llistrik, heat, flow, magnetic, and others. The birth of calculus is considered as the starting point of modern civilization progress.
Nevertheless, the discovery of Newton's law of Newton until today are very helpful. Did you know that Isaac Newton's laws of motion successfully developed when he was 23 years old? Newton's laws are still regarded as a law of nature that underlie the study of mechanics. Newton's laws Newton's laws I and III associated with statics, whereas Newton's second law relates to the dynamics.
Newton in developing its laws, many based on the ideas and the results of Galileo's ideas, a great scientist who succeeded in laying a solid foundation of the concept of motion and acceleration concepts through experiments in the tower of Pisa and the inclined plane. Indirectly, the Newton law Galileo was born from the inspiration that is understood by Newton himself.
Newton's laws
Newton's laws can and have been applied to so many scientific and engineering problems. Newton also pave the way in the field of astronomy. In his great work Mathematical Principles of Natural Philosophy which presents the laws of gravity and the laws of motion. Newton showed how these laws can be used to predict the movement of planets around the sun exactly.
Newton's Laws of Motion
Sir Isaac Newton (1642 - 1727) is a British scientist who studied the dynamics. Dynamics is the branch of physics that studies the motion of an object. Newton's law of motion of the underlying mechanics of motion in the presence of the branch of Physics. Newton's laws of motion is divided into three, namely the law of Newton I, Newton's second law and Newton's third law.
Newton's laws are very close to our daily lives. You include people who put a seat belt when driving? Yes, in fact, seat belts have an important function. Seat belts are useful to protect the body so as not to collide when the collision occurred.
When the car brakes suddenly, the body which originally spontaneously silence will be pushed toward the front. At the same time, the body is actually still trying to maintain his original position. Such was the style that can also be identified and attributed to Newton's famous law.
Even when you push a car that was breaking down. Newton's laws also apply. Encouragement is given to the car broke down, in Newton's law is called a style. Thus you see your child draw a car-mobilannya, in this case your child is also being issued a style. The style was later associated also with Newton's laws.
If an object falls, we say that it is because it is caused by the force of gravity. So, clearly defined that the force is a push or pull. Style does not always cause the motion. For example, you push a solid wall, but the wall was not moving. Understanding that is also connected with Newton's laws.
Newton's Laws I
I review about Newton's laws or the inert nature of the inertia of an object that has previously been suggested by Galileo. An object is inert means that an object is inclined to maintain the initial state of motion. The point is, if the object at rest, the object is likely to want to always be quiet and if the object is moving in circumstances likely to want to move on.
A large stone on the slopes of the mountain will remain stationary in place until there is another external force to move it. For example tektonisme style or earthquake. This phenomenon has been described in Newton's Law I.
Another example is related to Newton's laws I can feel in our daily lives. When you are on a train or a vehicle, which was originally kenadaraan still and not move all of a sudden move, at the same time your body will be attracted to the opposite direction of motion of the bukaa?
In conclusion I formulate Newton's laws of motion as follows:
Each object maintains the circumstances, still or moving uniformly straight, unless there are forces acting on it. The term force in the statement of Newton's laws I interpreted as a resultant force.
Mathematically, this law can be stated as follows:
If there is no resultant force acting on the object, then the objects will be stationary or moving uniformly straight.
Newton's Second Law
You never saw a football player in action on the ground? Kicking the ball with full power to score against your opponent. Did you notice the movement of the ball? Is the ball suddenly changed direction? The ball must have changed direction when a force about it. Movement of the ball can also be called as a form of Newton's laws.
The ability of objects to maintain state, both when moving and stationary turns out to have the size. Size for mentioning it is called inertia. Influenced inertia of the velocity the object itself, while the quality of its own inertia under the influence of the mass of the object. The formulation as it happens in Newton's laws.
If there is a resultant force arising on an object, the object will move with an acceleration that influenced style. If the object initially at rest and then will move then accelerated to a certain acceleration, while if an object is initially moving with constant velocity will change to be accelerated or slowed jusyru. It is stated in Newton's second law.
The conclusion that shorter is an acceleration produced by the resultant force acting on the object occurs, is directly proportional to the resultant force and inversely proportional to itself the mass of the object. Movement of objects that Terkenai style is a matter that exist in Newton's laws.
Newton's Third Law
Never upset to take it out on the wall? Beat him and then felt the pain? Actually this is also a reaction to the results of the force released when hitting the wall. Wall tells how large the force exerted by the force of the hand when hit by giving pain. The harder the blow given to the wall, the more it will hurt. The pain is felt also a picture of Newton's laws themselves.
This explanation clearly defined in Newton's Third Law which states that the amount of force that caused an object to be as large as the force exerted on the force. But his style opposite direction with a given reaction force on an object. Newton's laws - Starting from Gravity to Motion
