1. What is the upward force exerted by a fluid that opposes the weight of an immersed object?
Gravity
Buoyancy
Friction
Magnetism
2. An object will float if its density is:
Greater than the fluid
Less than the fluid
Equal to the fluid
Irrelevant to the fluid
3. Archimedes' Principle states that the buoyant force on an object is equal to the weight of the fluid displaced by the object.
True
False
4. A heavy object will always sink, regardless of its shape or density.
True
False
5. The amount of space an object occupies is called its .
6. If an object displaces a weight of fluid that is less than its own weight, the object will .
7. Explain why a large, heavy ship can float on water, but a small pebble sinks.
8. Observe the diagram below. Draw an arrow indicating the direction of the buoyant force acting on the submerged block.
