How many pressure apply for 1 kg weight?

Answer 1

It's a Physics question, post it else where.

Joking, even thought it's not a Math question, but we will help you.

The answer is: No one knows!

Pressure P = F/A where

F is the Force applied

A is the area of the object applying the force

so let's say the pressure of a 1kg thing apply weight force (gravitational) on the ground through a surface area of 1 cm ^2

Then P = F / A = mg / A = 1 kg x 10 N / kg x 1 / .01 m^2 = 1000 N

Now suppose it's the same object, same mass, but area is 1m ^2

Then

P = 1 kg x 10 N/ kg x 1/1 m^2 = 10 N

Both object is 1kg, but pressure is very different.
