Pressure

Pressure

Pressure is the normal force acting per unit area of a surface.

### Formula

$$P=\frac{F}{A}$$

### Terminologies

- P → Pressure.

- F → Normal force.

- A → Area of surface.

### SI Unit

$$Pascal(Pa)$$

### Dimensions

$$[P]=[ML^{-1}T^{-2}]$$

### Conditions / Special Cases

Pressure increases when area decreases.

### Usage

- Used in fluid mechanics and pressure calculations.
