Here's why:
* Pressure is defined as force per unit area: Pressure = Force / Area.
* If you keep the force constant and double the area, the pressure is divided by two.
Think of it this way:
* Imagine you're standing on a bed of nails. If you stand on two nails, the pressure on each nail is higher than if you stand on ten nails. The force (your weight) is the same, but the larger area distributes the pressure more evenly.
Example:
* If you apply 10 Newtons of force to a surface of 2 square meters, the pressure is 10 N / 2 m² = 5 N/m².
* If you double the area to 4 square meters, the pressure becomes 10 N / 4 m² = 2.5 N/m².
