I don't have a degree in physics so I can 't make it accepted. It is an excellent important idea it mustn't bury forever . How I solve this?
What if Newton's laws are still unknown and someone with only mechanics background discovered them how it will be accepted if he do not have a physics degree?
so you can realize that when you stand on your toes the reading on the scale should not double. In other words your idea is incorrect.
Why it should not double ?
I press the scale with the force I lift my body with which should make the scale read double it is basic physics.

If it is not doubled what value should be and why?
Let's say you then stand on your toes. You will elevate your body about 15cm. Let's assume it takes 1/2 second to raise on your toes. That would give you roughly an acceleration of 30 cm/s^2 or about 0.3 m/s^2.
Your body won't accelerate until there is a net force on it. Gravity and the normal reaction force are in equal proportion but opposite directions, so there is no net force on your body. When you stand on tip toes you only need to produce the tiniest amount of additional upward force. Since there was no net force to start with, ANY extra force will be a net force on your body. So your body starts to accelerate and you effectively lift yourself up on to your toes.
Any tiny extra force will cause a net acceleration.
If you have a block on the ground of 20 kg it has gravity force and normal force yet you need a net force equals the weight 196 N to accelerate it upwards.
@Origin , your calculation had some minor errors but it doesn't really matter too much. In some places you were mixing the average speed required to reach 15cm in ½ second with the acceleration that would be required.
this is futile, it will keep going round in circles.
Because I try as hard as I can but nobody understands or accepts
Because I try as hard as I can
The thing is, if you try hard enough, then you can make your model work,
There is no absolute truth in a scientific theory
