Introduction
The “Laws of physics” are the fundamental
rules that govern the behaviour of the
universe. To put it simply, the universe is an
incredibly complex machine and these laws
are the instruction manual.
These laws are extremely special as they
are universal, consistent and can be
expressed mathematically.
The laws of physics help us understand all
the underlying principles of the universe
that allows us to explain various
phenomena, make predictions and develop
new technologies. It is important to
comprehend that these laws are not made
up by humans but discovered by them
through careful observation,
experimentation and logical reasoning about
the natural world.
To understand this with an example, we
know why planets orbit the sun due to laws
discovered by Sir Isaac Newton and Sir
Michael Faraday.
,Overall, it is very important as physics
cannot exist without these laws.

, Law of conservation of Energy
Statement: “Energy cannot be created or
destroyed; it can only be transformed from one
form to another.”
While the form of energy might change, the total
amount of energy remains constant over time.
Discovery: This law was not discovered by a
single person but Julius Robert Mayer has been
given the credit for stating this law correctly.
Mathematical
Formulation
K1 = initial kinetic energy; K2= final kinetic energy
K1+U1= K2+U2
U1 = initial potential energy; U2 = final potential
energy
Applications:
A swinging pendulum demonstrates the
continuous conversion between potential energy
and kinetic energy. The total mechanical energy
(potential + kinetic) remains constant, assuming
minimal air resistance and friction.
The potential energy of water stored behind a
dam is converted into kinetic energy as it flows
downwards, which then turns turbines
(mechanical energy) to generate electricity
