Density quiz
density formula
D = M/V
(T/F) If you were to land on the Moon, your mass and your weight would be the same as they are on Earth.
False; because the Moon has a different gravitational pull than Earth, your weight would be different, but not your mass.
(T/F) Density is the amount of space an object takes up.
False; density is a measurement of how much matter is packed into a certain volume of a substance
(T/F) Water displacement is a method used to find the mass of an irregularly shaped object.
False; water displacement is a method used to find the VOLUME of an irregularly shaped object.
(T/F) Matter is the amount of gravitational pull on an object
False; weight is the amount of gravitational pull on an object.
(T/F) You need to know the weight and mass of an object in order to calculate its density.
False; you need to know the VOLUME and MASS of an object in order to calculate its density.
mass formula
M = DxV
(T/F) If an object has a greater density than water, it will sink.
True
(T/F) If you were measuring the shape of a box, you would use a ruler instead of water displacement.
True
(T/F) Mass can be measured in kilograms (kg)
True
(T/F) Milliliters (mL) are used to measure volume.
True
volume formula
V = M/D
definition of density
a measurement of how much matter is packed into a certain volume of a substance

lower
units for volume
mL or cm^3
definition of mass
the amount of matter in an object or substance
definition of volume
