Here's a breakdown:

* Pressure is defined as the force applied perpendicularly to a surface, divided by the area of that surface.

* Formula: Pressure = Force / Area

* Units: The standard unit for pressure is the Pascal (Pa), which is equal to one Newton per square meter (N/m²).

Examples of pressure:

* Atmospheric pressure: The weight of the air above us creates pressure on the Earth's surface.

* Water pressure: The weight of water in a pool or ocean exerts pressure on the bottom and sides of the container.

* Tire pressure: The air inside a tire exerts pressure on the tire's inner surface, helping it maintain its shape and support the weight of the vehicle.
