Important Theorems and Equations in Physics for UPSC Physics Optional Subject
1. Newton's Laws of Motion
- First Law: Also known as the law of inertia, it states that an object at rest will remain at rest, and an object in motion will continue to move with a constant velocity unless acted upon by an external force.
- Second Law: This law states that the rate of change of momentum of an object is directly proportional to the applied force and takes place in the direction in which the force is applied. The mathematical representation of this law is given by F = ma, where F is the force, m is the mass of the object, and a is the acceleration.
- Third Law: According to this law, for every action, there is an equal and opposite reaction. When one body exerts a force on another, the second body simultaneously exerts a force that is equal in magnitude and opposite in direction on the first body.
2. Laws of Thermodynamics
- First Law: Also known as the law of conservation of energy, it states that energy cannot be created or destroyed, but it can only be converted from one form to another or transferred from one system to another.
- Second Law: This law defines the concept of entropy and states that the entropy of a closed system always increases over time. It also establishes the direction of heat flow, which is from a higher temperature region to a lower temperature region.
- Third Law: This law states that as the temperature approaches absolute zero, the entropy of a system approaches a minimum value. It provides a basis for understanding the behavior of systems at extremely low temperatures.
3. Maxwell's Equations
- Gauss's Law for Electric Fields: This equation relates the electric flux through a closed surface to the charge enclosed within that surface. It is given by ∮E · dA = Q/ε₀, where E is the electric field, dA is the area vector, Q is the total charge enclosed, and ε₀ is the permittivity of free space.
- Gauss's Law for Magnetic Fields: This equation states that the total magnetic flux through a closed surface is always zero. It implies that there are no magnetic monopoles and that magnetic field lines always form closed loops.
- Faraday's Law of Electromagnetic Induction: This law describes how a changing magnetic field induces an electromotive force (EMF) in a closed loop of wire. It is given by ∮E · dl = -dφ/dt, where E is the induced electric field, dl is the line element along the closed loop, and dφ/dt is the rate of change of magnetic flux through the loop.
- Ampere's Law with Maxwell's Addition: Ampere's law states that the circulation of the magnetic field around a closed loop is directly proportional to the current passing through the loop. Maxwell
