New Theories / Re: The theory of the human body special mass
« on: 07/04/2022 18:58:07 »There are two options in the experiment:A human mass can be treated as a smaller mass when a human lifts or moves his own body.No it can't.
Whether the person lifts his body mass 60 kg with x kg or the x kg lifts a smaller mass of human body x kg
I chose the body to be smaller mass x kg because of the observation below:
I am completely baffled by the fact that you don't seem to understand that carrying a 60 kilogram rock means your legs are carrying more total weight than if they only had to carrying your own body weight without a rock.I said jump high and barely move the rock
Doubling the load 120 kg must not give the big difference but it did, a very easy 60 kg"body" vs a very difficult 120 kg"body+the rock"
can't you see the difference between jumping with high speed against gravity with even exerting your greatest force to lift a rock of 60 kg.
