Front

What is the unit of measurement for pressure?

Back

Pascal (Pa) is the SI unit of pressure.

Front

How do we calculate the area in the pressure triangle?

Back

Area is calculated using the formula: Area = Force ÷ Pressure.

Front

What is the equation used to calculate pressure?

Back

Pressure = Force ÷ Area.

Front

What decreases as you go up in the atmosphere?

Back

Air Pressure decreases as altitude increases.

Front

What is the relationship between force, area, and pressure?

Back

Pressure is directly proportional to force and inversely proportional to area.

Front

What is atmospheric pressure?

Back

Atmospheric pressure is the pressure exerted by the weight of air in the atmosphere.

Front

What happens to air pressure as altitude increases?

Back

Air pressure decreases with increasing altitude.

Front

What is the formula for calculating force?

Back

Force = Pressure × Area.

Front

What is the significance of the pascal in real-world applications?

Back

The pascal is used to measure pressure in various fields, including meteorology and engineering.

Front

How does temperature affect air pressure?

Back

As temperature increases, air pressure typically decreases due to the expansion of air.
