Formulas and Equations to Memorize for the Physics Optional Subject
1. Classical Mechanics
- Newton's Laws of Motion: F = ma, where F is the force, m is the mass, and a is the acceleration.
- Gravitation: F = G * (m1 * m2) / r^2, where F is the gravitational force, G is the gravitational constant, m1 and m2 are the masses of two objects, and r is the distance between them.
- Work and Energy: W = F * d * cos(theta), where W is the work done, F is the force, d is the displacement, and theta is the angle between the force and displacement vectors.
- Momentum: p = mv, where p is the momentum, m is the mass, and v is the velocity.
- Rotational Motion: I = mr^2, where I is the moment of inertia, m is the mass, and r is the perpendicular distance from the axis of rotation.
2. Electromagnetism
- Electric Field: E = k * (Q / r^2), where E is the electric field, k is the Coulomb's constant, Q is the charge, and r is the distance from the charge.
- Gauss's Law: ∮E * dA = Q / ε₀, where ∮E * dA is the electric flux, Q is the charge enclosed by the surface, and ε₀ is the permittivity of free space.
- Magnetic Field: B = (μ₀ * I) / (2πr), where B is the magnetic field, μ₀ is the permeability of free space, I is the current, and r is the distance from the wire.
- Ampere's Law: ∮B * dl = μ₀ * I, where ∮B * dl is the magnetic flux, μ₀ is the permeability of free space, and I is the current enclosed by the loop.
- Faraday's Law: ε = -dΦ / dt, where ε is the induced electromotive force, dΦ is the change in magnetic flux, and dt is the change in time.
3. Thermodynamics
- First Law of Thermodynamics: ΔU = Q - W, where ΔU is the change in internal energy, Q is the heat added to the system, and W is the work done by the system.
- Second Law of Thermodynamics: ΔS ≥ 0, where ΔS is the change in entropy.
- Entropy: ΔS = Q / T, where ΔS is the change in entropy, Q is the heat added to the system, and T is the temperature.
