Physics equations are mathematical expressions that describe the fundamental laws of the physical world. They are used to model and predict the behavior of natural phenomena, from subatomic particles to entire galaxies.
• In classical mechanics, Newton's equations describe the motion of objects based on the forces applied to them.
• In electromagnetism, Maxwell's equations describe the behavior of electric and magnetic fields.
• In quantum mechanics, the Schrödinger equations are fundamental to quantum mechanics and describe the temporal evolution of the wave functions of quantum particles.
• In special and general relativity, Einstein's equations describe the structure of space-time and gravitational effects.
• In particle physics, the Standard Model equations are used to describe the interactions between fundamental particles and fundamental forces.
