IGCSE Coordinated Science: Pressure

IGCSE Coordinated Science: Pressure

Pressure

1. Relate (without calculation) pressure to force and area.

Pressure is simply the force exerted divided by the area the pressure is exerted on.

2. Recall and use the equation P = F/A.

I’m just going to do some GCSE style questions which I will update quite regularly.

Pressure = Force ÷ Area

Force measured in Newtons

Area measured in square meters

So pressure is measured in : Pascals (Pa)

1) An office table has a weight of 600N. If the area of the base is 3.0 sq metres, what is the pressure on the floor of the office?

This question is dead simple. Simply take the Force (600N) and divide by the area (3.0 sq metres) to get

600N/3 sqmetres

=200 Pa
