Newton's laws of motion are the backbone of all things physics-related. They explain why things move, why things stop moving, and how things are able to defy gravity (minus the whole superhero aspect). From circular motions that make you dizzy to linear motions that take you straight to the refrigerator, Newton's laws are the rules that govern our everyday lives. They quantify physical quantities, break down the cause of action, and even provide us with fluid formulas that let us know what happens when we run out of coffee (spoiler alert: it's not pretty). In short, Newton's laws of motion is the ultimate guide to understanding how everything moves, except for your boss when it's time for a raise.
