WorksheetsArchimedes' Principle Part 1
Total questions: 10
Worksheet time: 6mins
What does Archimedes' Principle state?
An object will always sink in water if its mass is greater than 1 kg.
A body immersed in a fluid experiences an upward buoyant force equal to the weight of the displaced fluid.
Objects float only if they are hollow inside.
The force of gravity does not act on objects in a fluid.
What is the primary reason a ship made of steel can float in water?
The ship is moving fast enough to stay above water.
The ship is filled with air, reducing its overall density
The ship is not affected by gravity while in water.
The weight of the ship is greater than the buoyant force.
If an object is fully submerged in a fluid, what determines the buoyant force acting on it?
The object's volume
The object's weight
The density of the fluid and the volume of the displaced fluid
The depth of the object in the fluid
An object will float on water if:
Its weight is greater than the buoyant force.
It displaces more water than it weighs.
Its density is less than the density of water.
It is heavier than an equal volume of water.
What happens to the buoyant force when an object is placed in a denser fluid?
It decreases because denser fluids provide less support.
It stays the same because buoyant force depends only on the object.
It increases because a denser fluid exerts a greater buoyant force.
It disappears because the object is more likely to sink.
What is the SI unit of buoyant force?
Newton (N)
Pascal (Pa)
Kilogram (kg)
Joule (J)
A solid object weighs 50 N in air and 30 N when fully submerged in water. What is the buoyant force acting on it?
20 N
30 N
50 N
80 N
Which of the following statements is true about objects in a fluid?
Objects denser than the fluid always float.
Objects less dense than the fluid always sink.
Objects experience an upward force equal to the weight of the displaced fluid.
The buoyant force depends only on the object's mass.
If a block of wood floats on water, what can be said about the weight of the block compared to the buoyant force?
The weight is greater than the buoyant force.
The weight is equal to the buoyant force.
The weight is less than the buoyant force.
The buoyant force does not act on the block.
How does the volume of displaced fluid compare to the volume of a submerged object?
It is always greater than the object's volume.
It is always equal to the object's volume.
It is always less than the object's volume.
It depends on the object's density.
