4. Which of the following is TRUE about the second law of motion? A. The acceleration of an object is directly proportional to the magnitude of the net force acting on it and is inversely proportional to its mass. B. The acceleration is directly proportional to the mass and inversely to the net force. C. The mass is inversely proportional to the force and directly proportional to the acceleration. D. The net force is directly proportional to the mass and acceleration.
beacuse The acceleration of an object as produced by a net force is directly proportional to the magnitude of the net force, in the same direction as the net force, and inversely proportional to the mass of the object.
