Pressure

Pressure is the force per unit area applied in a direction perpendicular to the surface of an object. Therefore, the smaller the area, the less the pressure.
For example:


The cuboids are identical however, the cuboid on the left exerts less pressure than the one on the right. This is because the cuboid on the left has less area applied perpendicular towards the fore, weight.
