Of course the weight measured by the scale increases, as others explained. (Otherwise things would be really strange!)chad6889 said:... if you have a fish bowl half filled with water sitting on a scale, then you add 3 goldfish does the weight increase?
I wonder if the displacement might be confusing them. If the bowl was full of water, adding fish would dump some of it out. Obviously, when there's enough bowl to hold it all, that doesn't happen.Doc Al said:The bottom line is that the force that the scale exerts on the bowl (which is what the scale measures) must equal the total weight of the bowl and everything in it.
