By nature, laws of Physics are stated facts which have been deduced and derived based on empirical observations. Simply put, the world around us works in a certain way, and physical laws are a way of classifying that “working.”

Physical laws are just conclusions drawn based on years (or however long it takes) of scientific observations and experiments which are repeated over and over under different conditions to reach inferences which can be accepted worldwide. These are continuously validated by the scientific community over time.

In the beginning, it was assumed that the earth was the centre of the universe. Then it was hypothesized that our sun is the centre of the universe. We now know that both these conclusions are wrong. The sun may be the centre of our solar system, but it is not the centre of the universe.

Another example is the odd behaviour of the planet, Mercury. Newton’s universal law of gravitation was able to explain all the other planets in the solar system but the orbit and rotational period of Mercury was a bit off, and for some time no one knew why. Later, Einstein came to the rescue with his general theory of relativity.

The different properties of laws of Physics which shed information about their nature are given below:

- True, under specified conditions
- Universal and do not deviate anywhere in the universe
- Simple in terms of representation
- Absolute and unaffected by external factors
- Stable and appear to be unchanging
- Omnipresent and everything in the universe is compliant (in terms of observations)
- Conservative in terms of quantity
- Homogeneous in terms of space and time
- Theoretically reversible in time

Basic laws of physics that govern our universe can be categorized in two ways. Classical physics that deals with us, the surrounding environment and the observable universe around us. Apart from this, there is also atomic physics that deals with subatomic particles and their interactions (quantum mechanics).

There are so many laws of Physics which deal with various elements in the world. But all these laws of Physics are categorized into two:

- Classical mechanics: These laws deal with elements that are observable.
- Quantum mechanics: These laws deal with atomic and subatomic particles.

The three laws of Physics refers to Newton’s three laws of motion as follows:

- Newton’s first law
- Newton’s second law
- Newton’s third law

Newton’s three laws are as follows:

- Newton’s first law of motion: The law states that a body will remain at rest or in uniform motion on a straight line until an external force acts on it.
- Newton’s second law of motion: The law states that the rate of change of momentum is proportional to the external force acting on it.
- Newton’s third law of motion: The law states that for every action there is an equal and opposite reaction.

Following are the seven laws of the universe:

- The law of mentalism (immutable)
- The law of correspondence (immutable)
- The law of vibration (immutable)
- The law of polarity (mutable)
- The law of rhythm (mutable)
- The law of cause and effect (mutable)
- The law of gender

There are 12 laws of the universe as follows:

- The law of divine oneness
- The law of vibration
- The law of action
- The law of correspondence
- The law of cause and effect
- Law of compensation
- The law of attraction
- The law of perpetual transmutation of energy
- Law of relativity
- Law of polarity
- Law of rhythm
- Law of gender
