    Force Lift
Click For Summary
A person weighing 60 kg exerts a force on a scale, which reads 600 N due to gravity. When the person pushes down with an additional force, the scale reflects this increased force, indicating a total of 600 + x N. For the person to lift off the scale, the total upward force must exceed 600 N, which occurs when the scale pushes up with a force greater than the weight. The discussion highlights the distinction between total applied force and net force, emphasizing that a net upward force is necessary for acceleration. Misunderstandings about energy conservation and force application are addressed, clarifying that a small additional force can still result in upward motion if it contributes to a net force greater than zero.

I did not die
Thanks a lot I appreciate it,
But this is not the idea you should not die you will just feel some pain without belly damage. You will damage your belly if you put a +100 kg rock " equals to your weight" on your belly. Post #109
You lie on the belly " your picture" by +100 kg weight you do not hurt your stomach. You put the same weight as a rock of +100 kg on your belly, that will damage your belly severely. Big different scenarios even though both are of the same mass.

The only thing I felt was my quark coming up

Obvious trolling.
I can go and get a tractor tire of weight ~180 kg and roll it up my stomach. Then you will say it is not good because tractor tires are round or whatever

I made this discovery. I must be one of the authors at least.

We will share the Nobel Prize, welcome to Stockholm! You can stand on my belly as much as you want!

Yep. Thread is closed; warning is pending. Everybody have a good day. :smile:
