## Explanation of Key Terms – Famous Equation In Physics

1. Mechanics:
– Newton’s Second Law: F = ma, where F is the force applied to an object, m is its mass, and a is its acceleration. This equation explains how the motion of an object changes when a force is applied to it. For example, when a car accelerates, the force applied by the engine (F) causes the car to move faster (a) if its mass (m) remains constant.

2. Electromagnetism:
– Maxwell’s Equations: These four equations describe the behavior of electric and magnetic fields. They include Gauss’s Law, Gauss’s Law for Magnetism, Faraday’s Law of Induction, and Ampere’s Law with Maxwell’s Addition. These equations explain how electric and magnetic fields interact and propagate. For instance, Faraday’s Law of Induction explains how a changing magnetic field induces an electric current in a wire.

3. Thermodynamics:
– The First Law of Thermodynamics: ΔU = Q – W, where ΔU is the change in internal energy of a system, Q is the heat added to the system, and W is the work done by the system. This equation states that the change in internal energy of a system is equal to the heat added minus the work done. It helps understand energy conservation in various processes, such as the conversion of heat into work in a heat engine.

4. Quantum Mechanics:
– Schrödinger’s Equation: This equation describes the behavior of quantum particles, such as electrons, in terms of wave functions. It determines the probability distribution of finding a particle in a particular state. For example, it can be used to calculate the energy levels of an electron in an atom.

5. General Relativity:
– Einstein’s Field Equations: These equations describe the relationship between the curvature of spacetime and the distribution of matter and energy. They explain how gravity arises from the geometry of spacetime. For instance, they predict the bending of light around massive objects, as observed in gravitational lensing.
