Chapter 4 Review: Buoyancy and Pressure

Front

What happens if the mass of an object is greater than the buoyant force?

Back

The object will sink.

Front

Which exerts more pressure: a high-heeled shoe or a boot?

Back

The bottom of the high-heeled shoe exerts more pressure than the boot due to a decrease in surface area.

Front

If an object's surface area is smaller, does it create more or less pressure?

Back

It creates more pressure.

Front

What happens to pressure when force increases?

Back

Pressure increases.

Front

What does Archimedes' Principle state?

Back

The buoyant force acting on an object equals the weight (force of gravity) of the fluid displaced by the object.

Front

Define buoyancy.

Back

Buoyancy is the ability of an object to float in a fluid due to the upward force exerted by the fluid.

Front

What is pressure?

Back

Pressure is the force applied per unit area.

Front

How does surface area affect pressure?

Back

A smaller surface area increases pressure, while a larger surface area decreases pressure.

Front

What is the relationship between buoyant force and weight of the fluid displaced?

Back

The buoyant force is equal to the weight of the fluid displaced by the object.

Front

What is the formula for pressure?

Back

Pressure = Force / Area.
