Forces and Fluids

Front

What is pressure?

Back

Pressure is the force applied per unit area, measured in Pascals (Pa).

Front

What is the formula for calculating pressure?

Back

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

Front

What is the SI unit of pressure?

Back

Pascal (Pa)

What is a pascal (Pa) a measurement of?

Back

Pressure

Front

What is a fluid?

Back

A fluid is a non-solid state of matter, which includes liquids and gases.

Front

What is the pressure in Pascals when a force of 500 N is applied over an area of 25 m²?

Back

20 Pascals

Front

What is the pressure exerted by a force of 200 N acting on an area of 10 m²?

Back

20 Pascals

Front

How does atmospheric pressure change with altitude?

Back

Atmospheric pressure decreases as altitude increases.

Front

What is buoyancy?

Back

Buoyancy is the upward force exerted by a fluid on an object immersed in it.

Front

What is the principle of Pascal's law?

Back

Pascal's law states that a change in pressure applied to an enclosed fluid is transmitted undiminished throughout the fluid.
