Welcome to high school physics formulas! Physics formulas are mathematical expressions that describe natural phenomena and relationships between physical quantities. They help us understand motion, forces, energy, waves, electricity, and many other concepts. Let's explore the fundamental formulas that form the foundation of physics.
Kinematics describes motion without considering the forces that cause it. The fundamental kinematic equations relate position, velocity, acceleration, and time. These four equations are essential for solving motion problems with constant acceleration. The velocity-time graph shows how velocity changes linearly with time when acceleration is constant.
Forces and energy are fundamental concepts in physics. Newton's second law relates force, mass, and acceleration. Work is done when a force moves an object through a distance. Kinetic energy depends on mass and velocity squared, while potential energy depends on height. Power measures how quickly work is done or energy is transferred.
Waves and electricity follow mathematical relationships. Wave speed equals frequency times wavelength. Coulomb's law describes electric forces between charges. Ohm's law relates voltage, current, and resistance in circuits. Electric power can be calculated using voltage and current. These formulas are essential for understanding electromagnetic phenomena.
Thermodynamics and modern physics complete our survey of high school physics formulas. Heat transfer depends on mass, specific heat, and temperature change. The ideal gas law relates pressure, volume, and temperature. The first law of thermodynamics expresses energy conservation. Einstein's famous equation shows mass-energy equivalence. These formulas form the foundation for understanding energy, matter, and the universe.
