Question #e64c5

Answer 1

P = F/A

Explanation:

Pressure is directly proportional to the force applied and inversely proportional to the area of contact.

Answer 2

Pressure is found by dividing the force acting on a surface by the area of that surface.

Explanation:

Mathematically, the relation can be written

`P=F/A`

So, pressure is force per unit of area. If you consider some of the units used to express pressure, you will find this relation expressed there:

"pounds per square inch"

"newtons per square metre"

The latter unit which is what we call a pascal, Pa (like in 101.32 kPa being standard atmospheric pressure). So 101.32 kPa means a pressure that causes 101 32o newtons of force to act on each one square metre of surface. That's a lot of force!
