Question

Newtonian mechanics could not explain ​

Answer 1

Answer:

The problem with Newtonian mechanics is that it doesn't describe correctly physical systems moving at high speeds (close to the speed of light) or either in a strong gravitational field. Einstein's Theory of Relativity correctly describes those systems.

Answer 2

"Some of the most basic features of atomic phenomena is Newtonian mechanics".

Explanation:

• Newtonian mechanics could explain fall of bodies using of motion. Movement of planets using Kepler's law which are derived from Newtonian mechanics. Flight of rockets can be explained using Newton's third law.
• But Newtonian mechanics fails to explain even basic features of atomic phenomena.
• The only drawback of Newtonian mechanics, which can be ignored at small relative speeds, but brings disastrous results for system at high relative velocity for some observer.
• The drawback is that, it considers speed of light and gravitational effect to be infinite. According to Maxwell's equations, speed of light is defined as,$c=\frac{1}{\sqrt{uE} }$
• But, velocity is relative. There is no such thing as absolute velocity. And the formula doesn't specify to which observer, speed of light is 299,795,638 m/s.
