Question

when do we exert more pressure on the ground, while standing or lying on the floor? give reason for your answer.

Answer 1

When we are standing as the area of contact is less hence pressure willl be more
As
$P = \frac{F}{A} \: \: \: \: \: F\: is \: force \: \\ A \: is \: area \: \\ pressure \: is \: inversely\\ \: proportional \: to \: area$
