What is this?

Physics formulas are mathematical relationships governing motion, energy, forces, waves, electricity, and gravity — the rules that describe how the physical world works.

Why does it matter?

Every bridge, engine, satellite, and medical scanner is designed using physics. These formulas let engineers and scientists predict precisely how things move, collide, and interact.

Key terms
Force (F) — a push or pull on an object; measured in Newtons (N) Velocity (v) — speed in a specific direction; metres per second (m/s) Acceleration (a) — rate of change of velocity; metres per second squared (m/s²) Energy (E) — capacity to do work; measured in Joules (J) Power (P) — rate of doing work; measured in Watts (W) Frequency (f) — wave cycles per second; measured in Hertz (Hz) Electric Field (E) — force per unit charge; N/C or V/m Coulomb's Law — force between two point charges: F = kQ₁Q₂/r²
