Question

One of the most significant differences between classical physics and modern physics is that energy is quantized. Briefly describe this idea and give an analogy on a macroscopic scale, i.e. what would it be like if baseballs and cars noticeably behaved in this way.

Answer 1

Energy quantization differs classical mechanics from Quantum mechanics. That means in Classical mechanics energy remains continuous but in Quantum mechanics energy increases or decreases in some quanta of energy (hv). There is another property named De Broglie wavelength , understanding this concept gives us basic idea at the level of microscopic and macroscopic level. The De Broglie wavelength associated with microscopic objects will be comparable to the size of objects but as at macroscopic level ( mass increases and velocity decrease) the wave associated with object will be in order of {10^(-30) } or even less.

If cars and baseball behaves in this way they will radiate energy in quanta not continuously.
