What Is Positive Air Pressure?

Positive pressure refers to the pressure perpendicular to the line of action, or normal pressure.

[zhèng y lì]

The pressure between objects in high school mechanics is usually referred to as positive pressure, such as

Pressure is the force of an object in motion that is perpendicular to the surface. If it is a plane, the positive pressure is perpendicular to the plane; if it is a surface, it is perpendicular to the tangent of the object. for example:

When a wooden block slides down from the top of an inclined plane without initial velocity, during its descent, you can decompose the gravity it receives orthogonally. It can resolve two forces, one parallel to the inclined plane and the other parallel to the inclined plane Vertical, the force perpendicular to the slope is the positive pressure of the block on the slope when the block is sliding. The force parallel to the slope is called the gliding force. ^[1]
