The resultant force is the single force that represents the vector sum of all individual forces acting on an object, determining the object's acceleration according to Newton's Second Law. It is crucial for understanding the net effect of multiple forces and predicting the motion of objects in various physical situations.

object's acceleration

Newton's Second Law states that the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass. This fundamental principle of classical mechanics is expressed by the equation F = ma, where F is the net force, m is the mass, and a is the acceleration.
