Advanced Activities: Race Cars

1.	Why do race cars have big engines and strong tires? (Check the correct answer.)
	So they can be driven really fast. So they can be driven really slowly and carefully. So they can be driven with great control. So they can be driven while wearing a helmet.

2.	Can cars go so fast that it is unsafe for the driver? (Answer yes or no.)
	Yes. No.

3.	Some cars race so fast the wind and the air flow around the car lifts it up a little. (Answer yes or no.)
	Yes. No.

4.	What force can help a race car driver control the car? (Check the correct answer.)
	Lift. Velocity. Downforce. Fat tires.

5.	What is added to a race car and produce downforce or downlift? (Choose more than one answer.)
	Upside down wings. Front air dams. Rear spoilers. Strakes. Plates. Side skirts.

6.	A race car can have inverted (upside down) wings on it which will produce a downforce instead of lift. (Answer yes or no.)
	Yes. No.

7.	The tires create drag for open-wheel race cars. This is due to the separation of flow behind the tires. Several tricks have been used to decrease this drag. Usually, a simple plate is used to divert the air around the tire, limiting the amount of flow separation. (True or false.)
	True. False.

8.	What energy saving technique in bicycle racing is also used by car racers? (Check the correct answer.)
	Speeding. Drafting. Cutting in front. Jet fuel.

9.	In early car racing the engine and tires of the race car were considered most important. Later, what part of the car design became more significant. (Check one answer.)
	Velocity. Body design. Lift. Front air dams.

10.	It would be impossible for a race car to ever go fast enough to break the sound barrier. (True or false.)
