What is the unit of measure for mass?
gram
If a substance has a large mass and a small volume, what can you conclude about it?
It is very dense
g/ml or g/cm3
What is unit of measure for density?
What do you use to find the volume of a regularly shaped object?
ruler and calculator
an object has a density of 5 g/cm3 and has a volume of 100 cm3. Its mass:
What is 500 g?
An object has a volume of 500 cm3 and a density of 2 g/cm3. Its mass :
What is 1000g?
Density 0.45 g/cm3. Will the object float or sink?
What is float?
What is the water displacement used for?
find the volume of an irregularly shaped object.
What is buoyancy?
an object floats when it is less dense than the liquid it's in
exists when the weight of the body is equal to the weight of an equal volume of the displaced fluid. A body in this state remains suspended, neither rising nor sinking, unless acted upon by an outside force?
What is Neutral buoyancy?
used to measure the mass of an object.
What is a balance scale, digital scale, triple beam balance?
If an object is less dense than water, what happens to it?
the object floats.
the amount of matter in an object.
What is mass?
1.0 g/mL or 1.0 g/cm3
What is the density of water?
Density of an object is 50 g/mL, the volume is 25 mL. the mass of the object: (50x25) Use a calculator
1250 g.
length x width x height.
What is the formula for volume of a regularly shaped object?
helps you find the formulas for density, mass and volume. I'll give you a hint:
2 words
first: David Copperfield
second: 3 equal sided object
What is the magic triangle?
the upward force that keeps objects afloat.
What is buoyancy?
