From what I've learnt, the pressure increases when the area is reduced. Taking the high heels as an example, the tip of high heels have a really small surface area which result in high pressure. But, in which direction does the pressure acts on? Is pressure similar to force? When the area of an object is increased, the pressure is reduced because the pressure is shared? Pressure is defined as force acting perpendicularly on per unit area, what does force per unit area mean? I need specific answers, please help.
