5 More Physics Equations Everyone Should Know

Physics is a fascinating and complex science that helps us understand the world around us. While there are countless equations that are essential to the study of physics, here are five more equations that everyone should know:

1. Ohm’s Law (V=IR): This equation relates voltage, current, and resistance in an electrical circuit. It states that the current flowing through a conductor is directly proportional to the voltage applied across it, and inversely proportional to the resistance of the conductor.

2. Bernoulli’s Equation (P + 1/2 * ρ * v^2 + ρgh = constant): This equation describes the conservation of energy in a fluid flow. It relates the pressure, velocity, and height of a fluid at any two points in a steady flow.

3. Snell’s Law (n1 * sinθ1 = n2 * sinθ2): This equation describes how light waves refract when passing through different mediums. It relates the angles of incidence and refraction to the refractive indices of the two mediums.

4. Faraday’s Law of Electromagnetic Induction (ΔΦ = -d/dt (B*A)): This equation describes how a changing magnetic field induces an electromotive force in a conductor. It forms the basis of the operation of generators and transformers.

5. Coulomb’s Law (F = k * |q1 * q2| / r^2): This equation describes the electrostatic force between two charged particles. It states that the force is directly proportional to the product of the magnitudes of the charges and inversely proportional to the square of the distance between them.

These equations are just a few of the many fundamental relationships in physics that help us explain the natural world. Understanding and applying these equations can deepen our appreciation for the beauty and complexity of the universe.
