Read each question carefully and provide your best answer. Show all your work for calculations.
1. Which of the following statements best describes Archimedes' Principle?
The buoyant force on an object is equal to the weight of the object itself.
The buoyant force on an object is equal to the mass of the fluid displaced by the object.
The buoyant force on an object is equal to the weight of the fluid displaced by the object.
The buoyant force on an object is independent of the fluid it is submerged in.
2. An object floats in water if its average density is:
Greater than the density of water.
Less than the density of water.
Equal to the density of water.
Irrelevant to whether it floats or sinks.
1. The upward force exerted by a fluid that opposes the weight of an immersed object is called .
2. An object will sink if the buoyant force acting on it is than its weight.
3. The density of fresh water is approximately g/cm³.
1. A ship made of steel can float because its overall density is less than that of water.
True
False
2. Buoyant force increases with the depth of an object in a fluid.
True
False
1. Explain why an object with a higher density than water can still float if it is shaped appropriately (e.g., a boat).
2. A block of wood has a volume of 500 cm³ and a mass of 300 g. Will it float or sink in water? Show your calculation.
Match each term on the left with its correct definition on the right.
1. Buoyant Force
a. The amount of matter in a given volume.
2. Density
b. The upward force exerted by a fluid that opposes the weight of an immersed object.
3. Displacement
c. The volume of fluid pushed aside by a submerged or floating object.
