Pressure.
The force pushing on a surface or area is called pressure. It is defined as the amount of force applied per unit area of the surface.
The force pushing on a surface or area is called pressure. It is calculated by dividing the force by the area over which the force is applied. Pressure is measured in units such as pascals (Pa) or pounds per square inch (psi).
is go to google anyone can type on here
This is usually expressed as weight or force per square area. In imperial measure (USA) pounds per square inch In Metric KG/meter2
A surface pushing up, equal and opposite to a force pushing against it
The force pushing up is called the normal force. It acts perpendicular to the surface an object is resting on, counteracting the force of gravity.
Pressure. (Note that the force must be perpendicular to the surface.) Pressure can my measured in Pascals (N/m2), psi (pounds/in2), atmospheres, or a few other units.
The pushing force acting upwards from the ground is called the normal force. It is a reaction force that occurs when an object is in contact with a surface and prevents the object from falling through the surface. The normal force is equal in magnitude and opposite in direction to the force exerted by the object on the surface.
The force of water pushing against you as you move through it is called drag force. It depends on factors like your speed, the water's density, and your surface area in contact with the water. It increases as your speed or surface area increases.
it is AIR PRESSURE
The quantity that is divided by the surface area is force. Force divided by surface area is equal to pressure.
The force pushing up is called the normal force. It is exerted upwards by a surface to support an object placed on it and counteract the force of gravity pulling the object downwards.
