Disadvantages Of Classical Mechanics

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,

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
