Pressure is defined as force per unit area. The standard unit for pressure is the Pascal, which is a Newton per square meter.

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

For an object sitting on a surface, the force pressing on the surface is the weight of the object, but in different orientations it might have a different area in contact with the surface and therefore exert a different pressure.

pressure acting sideways is known as lateral pressure .

Pressure can be defined as the force per unit area which can be written as $\dfrac{Force}{Area}$.

Although Force and Area, both are vector quantities, pressure is a scalar quantity.

Pressure affects substances in al the state whether it is liquid, solid or gaseous.

Pressure is the force acting on a unit area of a surface it can be written as pressure  $= \dfrac{force}{area}$

Pressure is force acting on a unit area of a surface when force applied on object in a particular area of object exert pressure on it.

When a force acts vertically downwards or normal to the surface under consideration, it is called thrust.
