5 More Physics Equations Everyone Should Know

Physics is a fascinating branch of science that helps us understand the fundamental laws governing the universe. In addition to the well-known equations like E=mc^2 and F=ma, there are several other important equations that every physics enthusiast should be familiar with.

1. Ohm’s Law: V=IR – This equation describes the relationship between voltage (V), current (I), and resistance (R) in an electrical circuit. It is fundamental to understanding how electricity flows in circuits.

2. Newton’s Law of Universal Gravitation: F=G(m1*m2)/r^2 – This equation explains the force of gravity between two objects with masses m1 and m2 separated by a distance r. It is crucial for understanding planetary motion and celestial mechanics.

3. Snell’s Law: n1*sin(theta1) = n2*sin(theta2) – This equation describes how light refracts when passing through different mediums with different refractive indices. It is essential for understanding optics and the behavior of light.

4. Wavelength-Frequency Relationship: c=λ*f – This equation relates the speed of light (c) to the wavelength (λ) and frequency (f) of a wave. It is crucial for understanding the properties of electromagnetic radiation.

5. Gauss’s Law: ∮E*dA = Qenc/ε₀ – This equation relates the electric flux through a closed surface to the charge enclosed within that surface. It is fundamental to understanding electrostatics and the behavior of electric fields.

By familiarizing yourself with these additional physics equations, you can deepen your understanding of the natural world and appreciate the beauty of the laws that govern it.
