What is the formula for calculating a Newton?

F = mv
F = m + a
F = ma
F = m/a

The correct answer is: F = ma

The formula for calculating a Newton, which is the unit of force in the International System of Units (SI), is expressed as F = ma. This formula indicates that force (F) is the product of mass (m) and acceleration (a). In other words, it describes how the mass of an object, when subjected to acceleration, will result in a force being exerted. Understanding this relationship is crucial in physics as it connects the concepts of mass, acceleration, and the resulting force. This formula is foundational in mechanics, reflecting Newton’s second law of motion, which states that the force acting on an object is equal to the mass of the object multiplied by the acceleration it experiences. This principle not only helps in solving problems involving objects in motion but also lays the groundwork for understanding more complex dynamics in physical systems.
