If we dead is the weight of our body is same?
Answers
1. Dead body compared to a live body: NO WEIGHT GAIN DIFFERENCE. Why? Dead bodies do not cancel out center of gravity, which is where the weight load is supported with no support from c-o-g. It just feels heavier; weighs the same. A live body can distribute its weight across anatomical areas while obviously a dead body cannot. Think, Sandbag effect. Dead body, the center of gravity is far from a living person’s c-o-g: gravity is not just exerting force on a person but also torque
2. Mass is a measure of inertia (resistance to acceleration, no?) of the body or the amount of matter in the body. Therefore, mass can be measured using a triple beam balance, for example. So from a physics approach, the body’s weight is not about poundage or kilgrams—it’s force (F) and as such F has Newton units (N). Recall, Sir Issac’s 2nd law: F=ma. Body’s weight therefore is F and what does gravity give it…a c c e l e r a t i o n (a). F=mg—→ mass = wgt/g. And as such MASS is WEIGHT ÷ ACCELERATION because of G. M is constant quanity (no matter where you are…anywhere on planet, does not matter). WEIGHT again is just the G-force on MASS.
3. The Dead Body Effect can be explained by physics, and it makes sense to me (and hopefully to others). The ground of reason, however, begins to shift and quake a little when the subject of post-mortem weight loss is thrown into the equation. A good movie to add to the intensity of the weight loss theory is, perhaps, 21 Grams, starring Benicio del Torro, Sean Penn, Naomi Watts. Not sure if Netflix or Hulu has the 2003 American drama on tap, directed by Alejandro González Iñárritu from a screenplay written by Guillermo Arriaga…but check Amazon for a DVD buy, if you’ve got interest and night off from work or a lazy Sunday. The movie’s central theme curiously begs the question “Does a 21g loss of weight in a dead body confirm that a (the) soul weighs exactly that?” Subtracting body fluid and gas release and other biological reasons, the answer is still a resounding “nope.” A little background on the 21g theory: Dr. Duncan MacDougall of Haverill, Mass. was fascinated with death to the point of obsessive pursuit of quantifying & quantitative the human soul, and all evidence of it. He believed the soul had a material like substance and, thus, could be weighed. Despite flawed experiments, the doctor published his 1907 findings in the Journal of the American Society for Psychical Research and American Medicine, medical journal. Understandably, MacDougall’s findings were rejected by the scientific-medical community.
