Which concept refers to the sum of all forces acting on a body resulting in a specific motion?

The concept that refers to the sum of all forces acting on a body, resulting in a specific motion, is known as Net Force. The net force is a vector quantity that combines all the individual forces acting on an object. When multiple forces are applied to a body, the net force determines its acceleration according to Newton's second law of motion, ( F = ma ), where ( F ) is the net force, ( m ) is the mass of the body, and ( a ) is the acceleration produced.

Understanding net force is crucial in analyzing how an object will move in response to the various forces acting upon it. If the net force is zero, the object remains in its current state of motion, whether at rest or moving at a constant velocity. Conversely, if the net force is not zero, the object will accelerate in the direction of the net force.

The other concepts, while related, describe different aspects of forces. The resultant refers to a single effective force obtained from the vector sum of two or more forces. Balanced force refers to a situation where multiple forces cancel each other out, resulting in a net force of zero. Force equilibrium describes a state where all forces acting on an object are balanced, leading to no change
