Newton’s second law relates an object’s acceleration to its mass and the net force acting on it. Does Newton’s second law apply to a situation in which there is no net force? Select the best explanation. A. Yes. The law applies and it tells us that the object has a nonzero acceleration. B. No. The law applies only to situations in which a net force acts. C. No. The law does not apply because a zero net force would produce...
