What is the formula for force?

The formula for force is defined by the relationship between mass and acceleration, famously formulated as Newton's Second Law of Motion. According to this principle, force is equal to mass multiplied by the acceleration it experiences. This means that if you have an object with a certain mass, the force acting on it will influence how quickly and in what direction it accelerates.

In the context of the provided options, the correct choice aligns with this foundational physical law. When a force acts on a mass, that mass will accelerate proportionally to the force applied. This understanding is crucial in fields such as physics and engineering, where predicting motion based on force is a fundamental concept.

The other options involve different physical relationships that do not directly define force in the context of motion and acceleration, making them less relevant when answering the question specifically about the formula for force.
