In depth
Scientific laws summarize what happens in nature (often as a mathematical equation), whereas scientific theories explain why and how it happens. Laws remain valid within defined domains of applicability.
Examples in the real world
Newton's Law of Universal Gravitation (F = G m1 m2 / r²), Hooke's Law (F = -kx), and Ohm's Law (V = IR).
