    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.

Are you absolutely certain? This might be the afterlife.

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 comming 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!
