The branch of science concerned with the ” nature and interaction ” of matter and energy.
- Classical Physics
The physics that existed before the formulation of the theory of relativity and of quantum mechanics.
It explains matter and energy only on a scale familiar to human experience.
2. Quantum mechanics
The branch of physics relating to the very small.
It describes how light and matter behaves at atomic stages.
In quantum mechanics, objects have probability of certain chance of being at point A, another chance of being at point B and so on.
3. Relativistic Mechanics
