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

lower

units for volume

mL or cm^3

definition of mass

the amount of matter in an object or substance
