WebQuestion: (1) A force F is required to push a crate along a rough horizontal floor at a constant speed V with friction present. What force is needed to push this crate along the same floor a at constant speed 3V if friction is the same as before? A constant force 3F is needed. A force that gradually increases from F to 3F is needed. WebSince Newton's first law states that when the net force is zero, the object maintains a constant velocity. And for the net force to be zero, these forces have to cancel. So, even though it's non-intuitive, this cable force has to equal the force of gravity, so that the elevator can move with constant velocity.
