The basics

Air resistance is another name for which force?

AnswerDrag

Air resistance is drag in air.

The four forces on an airplane are lift, weight, thrust and what?

AnswerDrag

Thrust must overcome drag for a plane to fly.

What does a car's drag coefficient measure?

AnswerHow aerodynamic its shape is

Lower drag coefficients mean less air resistance.

Cyclists riding close behind one another to reduce drag is called what?

AnswerDrafting

The lead rider blocks air for those behind.

What is the classic distance of a drag race?

AnswerA quarter mile

Drag racing traditionally runs a straight quarter-mile track.

Expert level

Why do golf balls have dimples?

AnswerTo reduce drag so the ball flies farther

Dimples create a thin turbulent layer that reduces drag.

A falling object reaches terminal velocity when what happens?

AnswerDrag balances the force of gravity

With no net force, the object stops speeding up.
