Hello there :) First I'm sorry for my English it might be kinda bad ! I Have a little question about Weight and Pressure, Hope this is the right place. Here in this image we have 3 samples, A, B and C. They are 3 different types of shapes fulled with a liquid (let's say water) Talking about the physical pressure on the bottom of every shape :- In Sample (A) we can see that Weight = Pressure. In Sample (B) we can see that Weight < Pressure. In Sample (C) we can see that Weight > Pressure. Where did we get the extra pressure in the sample (B) ? It's like we create that green area from nowhere! And where did the extra weight go in the sample (C) ? It's like we lost that orange area and it's nothing! Hope I can fine the answer, Thank you :) !
