The weight of dead body are actually same . No increase or decrease in weight .. but body seems heavier bcz muscles of body are relaxed and including all sphincters of the body and also other cause is body didnot get support which makes it heavier... same thing happen when person become unconscious , u feel heavier in tht possition
A dead body has no weight difference compared to a live body. However a live body is able to do things that a dead body can not do. ... A dead weight basically means that the centre of gravity is where ever you are supporting the weighted load with no support from it. It feels heavier, but it weighs the same.
