Physics equations encompass a wide range of principles governing the physical world. Key equations include Newton’s Second Law (force equals mass times acceleration), kinematic equations relating velocity, displacement, and time, and thermodynamic laws like the First Law (change in internal energy equals heat added minus work done). Electromagnetic equations include Coulomb’s Law (force between charges) and Ohm’s Law (relation between voltage, current, and resistance). Wave equations describe wave speed, and Snell’s Law relates angles and refractive indices in optics. These equations form the mathematical foundation for understanding and predicting physical phenomena in different branches of physics.
