5 Most Famous Equations in Physics | 5 Most Important Physics Equations in History


Physics is a complex subject and it cover a wider area of our World. It contains so many Famous Equations in Physics which help us to understand the universe. One of the things that make physics so interesting is the use of equations to describe the behavior of the Physical world.

Out of these Famous Equations, One of the most is Einstein’s Energy-Mass Equivalence (E=mc²), which better understands the relationship between energy and mass.

The others are also important as Newton’s Second Law (F=ma), which explains the relationship between force, mass, and acceleration; the Schrödinger Equation, which base of quantum mechanics and explains the behavior of particles’ wavefunctions;

Maxwell’s Equations, a set of equations leading electric and magnetic fields and their behavior; and Planck’s Equation, which reveals the relationship between the energy of a photon and its frequency.

What are some of the most famous physics equations?

There are basically Five Equations which helps us to understand the whole physical world.

  • Einstein’s Energy-Mass Equivalence
  • Newton’s Second Law
  • The Schrödinger Equation
  • Maxwell’s Equations
  • Planck’s Equation

What are Physics equations?

                Physics equations are mathematical expressions that explain the relationships between different physical quantities. They are used to model and predict the behavior of physical systems, and they are essential tools for physicists.

Physics equations are typically written by using symbols and mathematical notation. They can be used to solve problems, to make predictions of an experiments, and to understand the underlying principles of physics.

Some of the most famous physics equations include:

Einstein’s Energy-Mass Equivalence: 

Mass Energy Equation by Albert Einstein

This equation,


states that mass and energy are equivalent.

In the above equation

E – Energy of a particle

m – mass of a particle

c – Speed of light

It is one of the most famous equations in the world, and it has had a great impact on our understanding of the universe.

Newton’s Second Law: 

This law states that the force acting on an object is equal to its mass times its acceleration.

F= ma

in the above equation

F- Force applied on an object,

m – Mass of an object

a- Acceleration produced in an object due to applied force.

It is one of the most fundamental laws of physics, and it is used to explain many phenomena, that can be like the motion of objects on Earth or the orbits of planets around the sun.

The Schrödinger Equation: 

This equation is the Base of quantum mechanics, and it Explains the wavefunction of a particle. The wavefunction is a mathematical object that have all the information about the particle’s state (i.e. its position, momentum, and energy).

Maxwell’s Equations: 

These equations describe the behavior of electric and magnetic fields.

They are one of the most important equations in physics, and this helps in explaining many phenomena present in electromagnetism.
