What happens when pressure is applied to a water bottle?
• When applying pressure to the water bottle with your hand the air will come out at a speed unknown and the computer will measure the pressure.
What happens to a table when you apply pressure to it?
• Nothing happens to the table Because you can not apply enough Force to break or crush the table.
Formula
P= F/A Pressure=P
Force= F
Area= A
The mass doesn’t change!!!
When you apply pressure to something the shape changes NOT the mass.
