What is pressure in fluids?

Force applied on a surface in a perpendicular direction.

How is trust defined?

Force applied on a surface in a perpendicular direction.

Inverse relationship, pressure decreases with increasing area.

Pressure increases with depth, higher in denser fluids.

Based on the height of mercury in a tube.

Trust is defined as the force applied on a surface in a perpendicular direction, with the unit of trust being Newton, and it is a vector quantity related to the weight of the body and the force of gravity.
Pressure is calculated by dividing force by area, with the unit of pressure being Pascal (Pa), and it varies with surface area, depth in fluids, and influences behaviors of gases and liquids.

This channel is exclusively for students, providing lesson content for Class Ninth Chapter Pressure in Fluids and Atmospheric Pressure.
Pressure is explained using examples like tractor tires and truck tires to illustrate the concept of force applied on a surface.
Trust is defined as the force applied on a surface in a perpendicular direction, with the unit of trust being Newton.
Trust is a vector quantity with both magnitude and direction, related to the weight of the body and the force of gravity.
The unit of trust is Newton, equivalent to force, and can also be measured in kilogram force or gram force.
Pressure is calculated by dividing force by area, with the unit of pressure being Pascal symbolized as Pa.
Pressure depends on area and trust, with an inverse relationship between pressure and area.
Examples like building foundations and slippers are used to explain how pressure varies with surface area.
Pressure in fluids increases with depth, with the pressure being higher in denser fluids like sea water compared to river water.
The pressure of a fluid at the top is lowest, increasing with depth, and higher density fluids have higher pressure.

Swimming is easier in water bodies with lower pressure, such as lakes, due to reduced pressure on the body.
The construction of dams involves creating concrete and iron walls to withstand the pressure of river water.
The deeper the wall in a dam, the more pressure it can handle from the river water.
Divers wear special protective suits due to the increased pressure at deeper ocean levels.
The size of bubbles in water increases due to decreasing pressure as they rise to the surface.
Pressure is exerted on fluids like gases and liquids, affecting their behavior.
Plungers are used to reduce pressure inside containers, allowing liquids to flow out.
Fountain pens operate by changing pressure to draw ink into the nib.
Barometers, like mercury barometers, measure atmospheric pressure based on the height of mercury in a tube.
Altimeters help determine altitude by measuring pressure changes at different heights above sea level.
