When something does not sink or float, we say it is ___________buoyant
Positively
Negatively
Neutrally
Floaty
If two objects are made of the same substance and have the same mass, the shape of the object determines whether or not it sinks or floats in a fluid.
True
False
If an object floats in water, the weight of the water displaced is greater than the weight of the body immersed in water.
true
false
If you put a brick in a tub filled to the top with water, the amount of water that overflows is equal to the volume of the brick.
true
false

What is the relationship between buoyant force and displaced fluid?
Buoyant force is equal to the weight of the displaced fluid
Buoyant force is greater than the weight of the displaced fluid
