ohh okay so the weight would be the same on the ground if its moving up at a constant speed?
October 26, 2009

physics
so the it would be the least on the way down, b/c your force, pushing on the scale is less. And it is greatest on the way up, since your force of push is stronger. And I would say in free fall it is the same as ground state?
