Air and Flight PAT Review

Use the following information to answer question 1. A paper rotor is made by cutting and folding paper. Which force causes the downward movement of the paper rotor?

• Lift

• Drag

• Thrust

• Gravity

Which of the following examples most clearly demonstrates the compression of air?

• Flying a kite

• Inflating a tire

• Blowing out a candle

• Using a vacuum cleaner

Use the following information to answer question 3. The observed airplane should be classified as part of

• Group I

• Group II

• Group III

• Group VI

The function of the fins on the rocket is to

• reduce drag

• generate lift

• provide stability

• streamline shape

Use the following information to answer this question. The chart below lists the results of an experiment with parachutes.

• The larger the hole in the canopy, the slower the parachute will descend.

• The length of the shroud lines has little effect on a parachute’s rate of descent.

• Parachutes descend more slowly as the number of paperclips attached to them increases.

• Parachutes descend faster as the number of paperclips attached to them increases.

Parachutes cause objects to fall to the ground more slowly because they

• increase drag

• decrease lift

• increase gravity

• decrease propulsion

Which of the following shapes is expected to offer the least resistance to the flow of water?

• A.

• B.

• C.

• D.

Bernoulli’s principle states that increasing a fluid’s _____ i _____ causes the pressure that is exerted by that fluid to _____ ii _____. The statement above is completed by the information in row

• A. volume, increase

• B. volume, decrease

• C. speed, increase

• D. speed, decrease
