Newton's Second Law of Motion is expressed by which equation?

The equation representing Newton's Second Law of Motion is F=ma, where F stands for force, m represents mass, and a is acceleration. This fundamental principle states that the force acting on an object is equal to the mass of that object multiplied by its acceleration. This relationship shows that an increase in mass requires a proportionate increase in force to achieve the same acceleration, and conversely, for a given force, greater mass results in less acceleration.

In the context of physics, this equation is crucial for understanding how forces interact with mass and motion in a variety of scenarios. It lays the groundwork for analyzing the motion of objects under various forces, making it indispensable in both classical mechanics and aviation applications.

Other options lack this correct representation of Newton’s Second Law or represent different concepts. For instance, F=mg relates to weight, where g is the acceleration due to gravity, and F=mv represents momentum, which is a different principle. F=ma² improperly suggests that force is proportional to the square of acceleration, which does not align with established physics principles.
