Pressure

Front

What is pressure?

Back

Pressure is defined as the force applied per unit area on a surface.

Front

What is fluid pressure?

Back

Fluid pressure is the pressure exerted by a fluid at rest due to the weight of the fluid above it.

Front

How does fluid pressure differ from pressure in solids?

Back

Fluid pressure is generated by particle collisions in all directions, while solid pressure is typically exerted in a specific direction.

Front

What is the unit of pressure?

Back

The SI unit of pressure is the Pascal (Pa), which is equivalent to one Newton per square meter.

Front

What is the formula for calculating pressure?

Back

Pressure (P) = Force (F) / Area (A).

Front

Why do we use the perpendicular component of force in pressure calculations?

Back

It's the only component that actually contributes to pressure.

Front

What happens when a gas particle collides with the wall of its container?

Back

It applies a force to the wall, creating pressure.

Front

What is atmospheric pressure?

Back

Atmospheric pressure is the pressure exerted by the weight of the atmosphere above a given point.

Front

How does depth affect fluid pressure?

Back

Fluid pressure increases with depth due to the weight of the fluid above.

Front

What is gauge pressure?

Back

Gauge pressure is the pressure relative to atmospheric pressure.
