5.2 Buoyancy

What is buoyant force?

• An upward force exerted by fluids on an object.
• An downward force exerted by fluids on an object.

Density is the relationship between which two quantities?

• Mass and volume

• Mass and weight

• Volume and weight

How does an object's density affect the buoyant force acting on it?

• The more dense the object, the greater the buoyant force

• The less dense the object, the greater the buoyant force

• Density has no effect on buoyant force
