Welcome to basic physics formulas! Physics uses mathematical equations to describe how things move and interact. The most fundamental formula in mechanics is Newton's second law: F equals m times a. This tells us that force equals mass times acceleration.
Energy and work are fundamental concepts in physics. Work is force times distance. Kinetic energy is one-half mass times velocity squared - this is the energy of motion. Potential energy equals mass times gravity times height - this is stored energy due to position.
Motion formulas describe how objects move with constant acceleration. The first equation gives final velocity: v equals u plus a t. The second gives displacement: s equals u t plus half a t squared. The third relates velocity and displacement: v squared equals u squared plus 2 a s.
Electrical formulas describe how electricity behaves in circuits. Ohm's law states that voltage equals current times resistance. Electric power equals voltage times current. Power can also be calculated as current squared times resistance. These formulas help us design and analyze electrical circuits.
Finally, wave formulas describe oscillating phenomena. Wave speed equals frequency times wavelength. The period is one over frequency. These basic physics formulas - from mechanics to electricity to waves - form the foundation for understanding our physical world and are essential tools in science and engineering.
