The force that water and other fluids exert upward on an object.
gravitational force
surface tension
buoyant force
cohesive force
An object that is less dense than the fluid in which it is immersed will
sink
float
neither rise or sink
not displace any water
When water fills a submarine's flotation tanks, the overall density of the submarine
decreases
stays the same
depends upon the depth of the submarine
increases
A ship stays afloat as long as the buoyant force is
less than the ships weight
less than the ship's speed
equal to the ships weight
less than the ships density
The buoyant force acts in the direction opposite of this force.
gravitational force
surface tension
cohesive force
density
When an objects density is equal to the density of the fluid in which it is immersed.
positive buoyancy
neutral buoyancy
negative buoyancy
reverse buoyancy
When an object's density is less than the density of the fluid in which it is immersed.
neutral buoyancy
positive buoyancy
negative buoyancy
reverse buoyancy
When an object's density is greater than the density of the fluid in which it is immersed.
negative buoyancy
positive buoyancy
reverse buoyancy
neutral buoyancy
The volume of an object is equal the the amount of water the object displaces.
Einstein's Principle
Scooby Doo's Principle
Boyle's Principle
Archimedes' Principle
What determines how much water an object will displace?
It's volume
It's density
It's mass
It's temperature
An object has a mass of 200 grams and a volume of 50 cubic centimeters. What is the density of the object?
2 grams/cubic centimeter
4 grams/cubic centimeter
10 grams/cubic centimeter
20 grams/cubic centimeter
The amount of space an object occupies is its
mass
density
temperature
volume
An object that is more dense than the fluid will
sink
float
neither sink or float
sink then float to the surface
An object which has the same density as the fluid will
neither sink or float
sink
float, then slowly sink
float
