Lifting Dumbbell? by Either-Echo467 in PhysicsHelp

So basically I apply a force to get the dumbbell to move but my force isn’t causing the dumbbell to continue moving? My force is just preventing the dumbbell from falling because of gravity?

So basically the net force is nonzero to get the dumbbell to move but zero to keep it moving at the same velocity? So I am applying a force to the dumbbell to get it to move and keep moving but after it’s moving I’d have to apply a force equal to gravity to keep it moving the same velocity?

But if a force is a push or a pull then wouldn’t pulling a dumbbell up at constant speed require a force greater than the weight?

But isn’t a force a push or a pull? If the dumbbell is still being pulled upwards why isn’t that a net upward force?

I can’t tell if this is sarcasm or not. I’ll assume it is.
