**Density and Lift Worksheet
**

**Note: For Density Problems, use the formula D=M/V (Density =
Mass divided by Volume)**

For problems 1-4, use the mass and volume given to find the density of the column of air.

(1) Mass = 10 kg & Volume = 8m^{3}Density =_________(2) Mass = 15 kg & Volume = 10m

^{3}Density = _________(3) Mass = 5 kg & Volume = 2m x 2m x 2m (Hint: You first need to calculate the volume!)

Density = _________(4) Mass = 35 kg & Volume = 3m x 3m x 3m

Density = _________

**Now answer the following questions.**

(5) Looking at your answers above, which density will produce the greatest amount of lift?(6) Which will produce the least amount of lift?

(7) Given your answers to Problems 5 & 6 above, briefly state what effect the density of the air has on the lift of an airplane.
