Forces in Fluids

Front

What happens to water pressure as depth increases?

Back

Water pressure increases as depth increases.

Front

Are both liquids and gases classified as fluids?

Back

True, both liquids and gases are classified as fluids.

Front

What is the apparent loss of weight of an object in a fluid called?

Back

Buoyancy results in the apparent loss of weight of an object in a fluid.

Front

What is the SI unit used for measuring pressure?

Back

The SI unit used for measuring pressure is Pascals.

Front

What will happen to an object that is more dense than the fluid it is in?

Back

If an object is more dense than the fluid it is in, it will sink.

Front

What is the principle that explains why objects float or sink in fluids?

Back

The principle of buoyancy explains why objects float or sink in fluids.

Front

What is the relationship between density and buoyancy?

Back

An object will float if it is less dense than the fluid it is in, and sink if it is more dense.

Front

What is the formula for calculating pressure in a fluid?

Back

Pressure = Force / Area.

Front

What factors affect the buoyant force acting on an object submerged in a fluid?

Back

The buoyant force depends on the volume of fluid displaced and the density of the fluid.

Front

How does atmospheric pressure change with altitude?

Back

Atmospheric pressure decreases with increasing altitude.
