Pressure Principles

Front

What is buoyant force?

Back

The upward force exerted by a fluid on an object submerged in it, allowing objects to float or rise.

Front

True or False: All objects submerged in a fluid have a buoyant force, whether they are floating or not.

Back

True

Front

What principle explains the buoyant force on submerged objects?

Back

Archimedes' Principle.

Front

What principle states that an increase in the speed of a fluid occurs simultaneously with a decrease in pressure?

Back

Bernoulli's Principle.

Front

What decreases as you go up in the atmosphere?

Back

Air Pressure.

Front

What is the formula for pressure?

Back

Pressure = Force / Area.

Front

Back

10 Pa.

Front

What is viscosity?

Back

A measure of a fluid's resistance to flow.

Front

Back

high.

Front

What happens to air pressure as altitude increases?

Back
