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
