Classical & Modern

Branches of Physics

Classical Physics

• Includes topics which were developed up until the 1920’s and recognized before the beginning of the 20^th century.

• Focus on Newtonian Mechanics, Thermodynamics and Electromagnetic Theory

Modern Physics

• These are concepts which were developed and recognized since the beginning of the 20^th century.

• This includes topic concerned with the behavior of matter and energy under extreme conditions (very large or very small)

Isaac Newton

Father of Classical Physics

Albert Einstein

Father of Modern Physics

1. Law of Inertia

2. Law of Acceleration

3. Law of Action & Reaction

(IAA-3)

Three Laws of Motion

Law of Inertia

An object at rest stays at rest, and an object in motion stays in motion unless a force acts on it.

Law of Acceleration

​

F = ma (Force = mass × acceleration)

• The harder you push something, the more it accelerates.

Law of Action & Reaction

For every action, there is an equal and opposite reaction.
