When one object moves out of the way to make room for another object.
property
displacement
material
float
Weight and mass are the same thing
true
false
Archimedes' Principle states that
Buoyant force is equal to the mass of fluid displaced by an object.
Buoyant force is equal to the weight of the fluid displaced by an object.
What determines if an object will sink or float?
There is not enough information
The buoyant force compared to the weight of an object
The buoyant force compared to the volume of an object
Which of the following is dependent on gravity?
mass
weight
Buoyancy is the
upward force of a fluid
weight of an object
downward force of a fluid
If the density of an object is greater than the density of water, it will
sink
float
fly
If the density of an object is less than the density of water, it will
float
sink
The formula to find average density is
D= m/v
D=v/m
D=m X V
The density of water is
1 g/ml
10 g/ml
How do steel ships float, even though steel is denser than water?
Boats are not made of steel
Boats can only float in salt water
The density of the steel is reduced by hollowing out the boat to increase its volume.
Since a full ship has more mass than an empty ship, a full ship must displace more water to make it buoyant (make it float).
true
false
The less dense an object is means it will...
Float
Sink
The more dense an object is means it will...
Float
Sink
Displacement is when an object moves water to the side. This is so the object has room to take up that space.
True
False
Buoyancy is the tendency for objects to float in a fluid. We consider buoyancy the...
Un-gravity force
The upward force
Gravitational pull
Downwards pull on an object
Buoyancy is...
The ability or tendency to float in air, water or some other fluid
Degree of compactness of a substance
The moving of something from its place or position
A spring scale is used to measure weight. Which of the following does it measure?
The force of gravity on an object.
The amount of matter in an object.
The composition of an object.
The average density of an object.
Nick is preparing a solution and needs to measure the mass of some copper sulfate. Which one of the objects should he use to measure MASS?
Electric Scale
Ruler
Triple Beam Balance
Graduated Cylinder
Water is the only liquid objects can either float or sink in.
True
False
