The formula for calculating net force is the mass of the object multiplied by the acceleration. This formula is commonly written as "F = ma", where "F" represents the net force, "m" represents the mass and "a" represents the acceleration.

The formula for net force is based on Newton's second law of motion. The acceleration of an object is directly proportional to the net force, while the mass of the object is inversely proportional to the net force, as illustrated in the equation. Net force calculations are commonly done in the unit of Newtons, with the mass measured in kilograms and the acceleration calculated in meters per second squared.
