Which of the following relationships is correct?

The relationship m = F/a is correct when considering Newton's second law of motion, which states that the force applied to an object is equal to the mass of that object multiplied by its acceleration, denoted as F = ma. By rearranging this equation to isolate mass, you can see that mass (m) can be expressed as force (F) divided by acceleration (a).

This equation illustrates the fundamental relationship between mass, force, and acceleration in biomechanics and physics. It emphasizes that if you have a specific force applied to a mass, you can determine the mass if you know the acceleration. Understanding this relationship is crucial in biomechanics as it can help analyze how forces influence motion in living organisms and various physical systems.
