World Book Trivia Quiz For Kids-6/5-flight

1. What is the force that helps helicopters in the air?

Lift

Push

Pull

Most flying machines need wings. Wings produce a force called lift. Lift makes airplanes, helicopters, and other aircraft climb into the air and stay there.

3. Which country discovered how to make kites?

China

India

Greece

4. The first flight in a hot air balloon floated over which city?

Paris

London

Frankfurt

In 1783, two French brothers, the Montgolfiers, made a hot-air balloon. Two other Frenchmen floated over Paris in it. This was the first human flight.

5. Which part of the plane helps keep it balanced?

Tail

Wings

Fuselage

Most airplane wings have moving parts that help balance the plane. The ailerons are hinged pieces on the back of the wing. They make the plane bank, or tilt, and turn. Many planes also have flaps that help the plane lift up for takeoff and slow down for landing.

6. Who made the first flight that was faster than sound?

Robert H. Goddard

Charles E. Yeager

Colonel William Congreve

On October 14, 1947, Captain Charles E. Yeager of the U.S. Air Force made the first flight that was faster than sound. He flew a rocket-powered airplane called the X-1. In the 1960's, a rocket-powered airplane called the X-15 reached a speed of 4,520 miles (7,274 kilometers) per hour. This was more than six times the speed of sound

7. Amelia Earhart was trying to accomplish which task when she disappeared?

Fly to the north pole

Fly across the Atlantic Ocean

Fly around the world

Amelia Earhart > (1897-1937?) was an American aviator—an airplane pilot. In 1932, she became the first woman to fly alone across the Atlantic Ocean.
Earhart also tried to fly around the world. On May 20, 1937, she took off from Oakland, California, with her navigator, Frederick J. Noonan. On July 1, she took off from New Guinea. Her next stop was supposed to be Howland Island in the middle of the Pacific Ocean. But on the way, she reported that she was running out of fuel. Shortly after that, her plane disappeared. A massive search found no trace of Earhart, Noonan, or their plane. They likely crashed into the ocean and died.

8. What gas has the highest lifting power for hot air balloons

Nitrogen

Hydrogen

Helium

Hydrogen is the lightest gas, so it has the greatest lifting power. However, it is easily set on fire, so it can be dangerous. Helium gas is heavier than hydrogen, but it is much safer.

9. What is the most common type of helicopter?

Single-rotor

Twin-rotor

Propeller-rotor

The single-rotor helicopter is the most common type of helicopter. It has one main rotor, or set of wings, mounted above its body. It also has a second, smaller rotor on its tail. Twin-rotor helicopters have two main rotors.

10. Before they became known as blimps, what were they called?

Floaters

Air ships

Limps

Blimps were first built in the United States during the early 1900's. People first called them limps because they crumpled up when the gas was let out. The most common type was known as class B, so their name, Blimp, became blimp.
