... pointing upward (against gravity) while the sofa is moving forward. Since the force is not connected to the motion, no work is done. The second is that the sofa’s energy does not change: it is moving at constant speed, so it has the same amount of kinetic energy; it stays at the same height, so it h ...

... Newton's second law can be used to find the net force required to accelerate a given mass with a given acceleration. The direction of the net force is the same as the direction of the acceleration. The relationship can also be rearranged algebraically to solve for the acceleration or the mass. Examp ...
