Physical Science - Chapter 7 Review

Front

What is the principle that states all fluids flow from high pressure to low pressure?

Back

This principle explains that fluids move from areas of higher pressure to areas of lower pressure, which is fundamental in understanding fluid dynamics.

Front

True or False: There is more pressure on the bottom of an object than on the top of an object.

Back

True. This is due to the weight of the fluid above the object, which exerts pressure downwards.

Front

What does it mean for an object to be buoyant?

Back

An object is buoyant if it can float in a fluid, meaning it displaces a volume of fluid equal to its weight.

Front

Define 'fluid'.

Back

A fluid is any material that can flow and take the shape of its container, including liquids and gases.

Front

Where is water pressure greatest?

Back

Water pressure is greatest at the bottom of the ocean due to the weight of the water above.

Front

What is Archimedes' Principle?

Back

Archimedes' Principle states that an object submerged in a fluid experiences a buoyant force equal to the weight of the fluid it displaces.

Front

What is the relationship between pressure and depth in a fluid?

Back

Pressure increases with depth in a fluid due to the weight of the fluid above.

Front

What is the definition of buoyant force?

Back

Buoyant force is the upward force exerted by a fluid on an object that is submerged or floating in it.

Front

What happens to an object that is less dense than the fluid it is in?

Back

An object that is less dense than the fluid will float.

Front

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

Back

An object that is more dense than the fluid will sink.
