Thermodynamics: Thermodynamics is the branch of physics that deals with the study of heat and temperature, and their relationship with energy and work.Mechanics is essential for understanding everything from the motion of planets to the behavior of atoms. Mechanics includes topics such as kinematics, dynamics, and statics. It is the foundation of all other branches of physics. Mechanics: Mechanics is the branch of physics that deals with the study of motion, forces, and energy.In this article, we will explore some of the most important topics in physics and their significance. There are many important topics in physics, some of which have been studied for centuries, while others are relatively new. It is one of the most fundamental sciences, providing us with a deep understanding of the universe and its workings. Physics is a natural science that deals with the study of matter, energy, and the relationship between them. Physics Formula for Important Topics of Physics Energy Levels of Hydrogen Atom: E = -13.6eV/n^2.Binding Energy per Nucleon: BE/A = Δmc^2/A.Physics Formulas of Electricity and Magnetism Bernoulli’s Equation: P 1/2ρv^2 ρgh = constant.Physics Formulas of Atomic and Nuclear Physics F = Gm1m2/r^2 (Law of Universal Gravitation).n1sinθ1 = n2sinθ2, where n is the refractive index of the medium.īelow is the list of important Physics Formula: Physics Formulas of Mechanics It states that the ratio of the sine of the angle of incidence to the sine of the angle of refraction is constant. Snell’s Law: This law describes the refraction of light as it passes through a boundary between two different media.It is expressed as E = σT^4, where σ is the Stefan-Boltzmann constant. Stefan-Boltzmann Law: This law relates the total energy radiated per unit area of a black body to its temperature. ![]() ![]() It relates the pressure, volume, temperature, and number of moles of a gas. Ideal Gas Law: This equation describes the behavior of an ideal gas under various conditions.It states that the product of the pressure and volume of a gas is constant. Boyle’s Law: This law describes the relationship between the volume and pressure of a gas at a constant temperature.Einstein’s Mass-Energy Equivalence: This equation relates mass and energy and is expressed as E = mc^2, where E is energy, m is mass, and c is the speed of light.It states that the current flowing through a conductor between two points is directly proportional to the voltage across the two points and inversely proportional to the resistance between them. Ohm’s Law: This law relates the voltage, current, and resistance in an electrical circuit.F = k(q1q2/r^2), where k is the Coulomb constant. It states that the force between two charged particles is directly proportional to the product of their charges and inversely proportional to the square of the distance between them. Coulomb’s Law: This law describes the electrostatic force between charged particles.F = G(m1m2/r^2), where G is the gravitational constant. Law of Universal Gravitation: This law states that every particle in the universe attracts every other particle with a force that is directly proportional to the product of their masses and inversely proportional to the square of the distance between them.Third Law: For every action, there is an equal and opposite reaction. ![]()
