Topic 2 - Pressure

Suppose two people of equal weight, one a man and one a woman, tread on your foot.  If the man is wearing flat shoes and the woman is wearing stiletto heels, which one will hurt you the most?   Answer

How do we see

High Pressure

A FORCE acting over a SMALL AREA gives a HIGH PRESSURE

Low Pressure

A FORCE acting over a LARGE AREA gives a LOW pressure

Calculate the Pressure when a force of 20N acts over an area of 10cm2
