Question

3 difference between classical physics and quantum mechanics

Answer 1

$\huge\textbf{Classical Mechanics :}$


→ Deals with motion of macroscopic particles.

→ Mainly considered as the particle nature.

→ Based upon Newton's Law of Motion.

→ Ex :- Car, bus etc.

_________________________________


$\huge\textbf{Quantum Mechanics :}$


→ Deals with motion of macroscopic as well aa microscopic particles.

→ Considered as dual nature of matter.

→ Based on Schrodinger's Wave.

→ Ex :- electron, proton, neutron.

Answer 2

Answer:

Chemical Mechanics :

1. Classical mechanics describes the motion of a macroscopic object.

2. Classical mechanics cannot explain wave-practical duality.

3. In classical mechanics the system is continuous.

Example:- Car, bus, etc.

Quantum Mechanics :

1. Quantum mechanics describe the motion of microscopic objects.

2. Quantum mechanics explain wave-practical

duality.

3. Quantum mechanics predicts discreteness.

Example:- electron, proton, neutron.
