Pressure is defined as force per unit area:
* Pressure (P) = Force (F) / Area (A)
This means:
* If the force (F) increases while the area (A) stays the same, the pressure (P) will increase.
* If the force (F) stays the same but the area (A) decreases, the pressure (P) will increase.
Examples:
* Stepping on a nail: A small force applied over the tiny area of the nail's point creates a large pressure, which is why it can penetrate skin easily.
* Snowshoes: Snowshoes distribute your weight over a larger area, reducing the pressure on the snow and making it easier to walk.
* High heels: The small area of a high heel concentrates your weight, creating higher pressure on the ground.
In essence, pressure is a measure of how concentrated a force is over a particular area. The more force you apply to a smaller area, the higher the pressure will be.
