Newton's second law of motion states that the force acting on an object is equal to the mass of that object multiplied by its acceleration, which is mathematically expressed as \( F = ma \). This fundamental principle emphasizes the relationship between force, mass, and acceleration.

When you apply a force to an object, its acceleration will increase proportionally to the force applied, provided the mass remains constant. This means that if you know the mass of an object and the force applied to it, you can determine the acceleration by rearranging the formula to \( a = \frac{F}{m} \). Thus, the statement that "force is the product of mass and acceleration" accurately reflects this relationship outlined in Newton's second law, making it the correct statement.

The other statements do not adhere to Newton's second law. For example, stating that acceleration is inversely proportional to the applied force contradicts the law, as increased force results in increased acceleration, not a decrease. Similarly, claiming that mass is directly proportional to acceleration misrepresents the concept since mass is a constant factor in determining how much an object will accelerate under a given force. Lastly, the notion that acceleration is constant for any force applied is false, as different forces will yield
