Application of classical mechanics Before I am talking about the application that involves classical mechanics, let figure out what is the classical mechanics and what does it mean? And why it is important in our life? How does it involve in our life? And where it takes place when we need it? First, let me introduce the classical mechanics. Classical mechanics basically can be considered as a study of the motion of objects. When we are talking about physics, there must be a person we have to talk about, Isaac Newton, who is widely recognized as one of the most efficiency scientists of all time and as a key figure in the scientific revolution. As everybody know, Newton had evolved many physics thermos, such as Newton first law, second law, …show more content…
His height is about 1.9 meter and his rate is about 90.43% which mean most likely he will get point when he is doing penalty free throw. The angle is easy to calculate. Such use the formula, tan = , = 29.5 then from the first test we can easily get the answer for the initial velocity and the time to reaches to the basketry. The motion for this one is easy to analyze, but the physics or classical mechanical is very important in our life. However, it also has its disadvantages. Limitations of classical mechanics
1 from low speed to high speed
Classical mechanics is a summary from the daily life of mechanical movement out of the law, the speed of movement of objects in everyday life are low speed, and the speed is much less than the speed of light, such as a moving car, firing missiles, satellites and spacecraft, etc. therefore fully applicable to classical mechanics. Some microscopic particles under certain conditions it may be close to the speed of light, this speed is called speed. Fast-moving objects, classical mechanics no longer apply, and the early 20th century, the famous physicist Albert Einstein established the special theory of relativity, special relativity elaborated near the speed of light in order to comply with the laws of motion of

According to the early 20th century, the famous physicist Albert Einstein 's special theory of relativity build quality to the movement of objects with the speed increases. The quality of the relationship between the velocity of the object is ,
Where m0 is the mass of the object is stationary, m is the mass velocity of the object when the v, c is the speed of light in vacuum.
Visible when v << c, m ≈ m0; when v approaches c, m approaches infinity. Therefore, when the speed of the object is much smaller than the speed of light in a vacuum, classical mechanics is fully applicable; When an object approaches the speed of light, classical mechanics do not apply.
(2) the speed of the superposition principle in classical mechanics is no longer valid
Let the water in the river 's speed relative to the riverbank, the boat 's speed relative to the water, then in classical mechanics, the speed of the boat relative to the shore for (vector
Albert Einstein’s discoveries and theories have had a positively enormous effect on the world. Some of Einstein’s biggest impacting discoveries and theories are the theories of Special and General relativity, the Theory of Relativity, Brownian motion, the discovery of the photon, and Einstein’s creation of the equation E = MC^2. Perhaps Einstein’s most beneficial discovery is his formulation of E = MC^2 which is crucial for space-flight and can help today’s scientist in gathering knowledge about our universe.
Firstly, Newton’s first law of motion is an object tends to stay in the state they are in, unless another force is acted upon it. This law is also known as the law of inertia. When an object is in motion it would like to keep moving forever, but in reality it stops. It stops for various reasons such as air, the surface on which it traveling, gravity, and it may hit an obstacle. Therefore, that is why in space, any object would keep moving on forever because there is nothing there to stop it from mov...
Sir Isaac Newton made an enormous amount of contributions to the world of physics. He invented the reflecting telescope, proposed new theories of light and color, discovered calculus, developed the three laws of motion, and devised the law of universal gravitation. His greatest contribution to physics was the development of the three laws of motion. The first law was called the law of inertia; this law stated that, “Every object persists in its state of rest or uniform motion in a straight line unless it is compelled to change that state by forces impressed upon it.” The second law is called the law of acceleration; this law stated that, “Force is equal to the chan...
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
Beside its contribution to physics Einstein’s relativity also offered so many scientific bases for some breakthroughs and new technologies. We can divide the influences into two aspects.
If an object of mass 'm' moves at speed 'v'. Then we can say it has a
This aspect of relativity explained the phenomena of light bending around the sun, predicted black holes as well as the Cosmic Microwave Background Radiation (CMB) -- a discovery rendering fundamental anomalies in the classic Steady-State hypothesis. For his work on relativity, the photoelectric effect and blackbody radiation, Einstein received the Nobel Prize in 1921.
This equation shows that mass will not affect the speed of an object, proving that whatever the mass of an object, the speed will always remain the same if all the other factors are kept constant.
With the Scientific Revolution in full swing, Sir Isaac Newton became very interested in advanced science and philosophy. In fact, he...
Kinematics unlike Newton’s three laws is the study of the motion of objects. The “Kinematic Equations” all have four variables.These equations can help us understand and predict an object’s motion. The four equations use the following variables; displacement of the object, the time the object was moving, the acceleration of the object, the initial velocity of the object and the final velocity of the object. While Newton’s three laws have co-operated to help create and improve the study of
In 1905, Albert Einstein wrote his paper on the special theory of relativity (Prosper). This theory has the reputation as being so exotic that few people can understand it. On the contrary, special relativity is simply a system of kinematics and dynamics, based on a set of postulates that is different from those of classical mec...
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.
The second law is, “the relationship between an objects mass (m), its acceleration (a), and the applied force (f) is F= ma.” The heavier object requires more force to move an object, the same distance as light object. The equation gives us an exact relationship between Force, mass, and acceleration.
Furthermore, my Physics class that introduced classical mechanics has prepared me for my major in science in mathematics. This class helped me because the professor focused on the general solution to a problem by using a
Aristotle’s theory of motion is centered on this idea of a natural resting place. He believed that all motion was centered upon the object trying to reach its natural resting position. (Jones) Aristotle also used the principles of natural motion and violent motion to describe movements. Violent motion used to describe motion which has an external force used to move it (Fowler). A rock falling would be described as natural motion because its natural ten...
