F = ma

F = ma is a fundamental equation in physics known as Newton's second law of motion. It states that the force (F) acting on an object is equal to the mass (m) of that object multiplied by its acceleration (a). In simpler terms, it means that the more massive an object is, the more force is needed to move it, and how quickly it speeds up (acceleration) also depends on that force. This relationship helps us understand how objects move and interact, whether it's a car accelerating or a ball being thrown.
