The ballon is lighter than air.
It is harder to walk on moon than on earth
air is heavier than balloon, air rises
-- Inflate the balloon with some substance that is less dense than air. OR -- Inflate the balloon with air, then heat it after it is sealed.
The flame heats the air contained in the balloon. This causes the air to expand, thus it becomes less dense than the air surrounding the balloon. Once the air in the balloon is sufficiently less dense than the surrounding air to overcome the weight of the balloons materials, it will lift into the air.
Hot air has density less than the air surrounding the balloon. When the average density of the balloon filled with hot air is less than the density of the air outside upthrust is more than the weight of the balloon. therefore it keeps on rising up till the upthrust becomes equal to the weight of the balloon.
Balloon is lighter than air.
No moving parts!
I guess they had a dream of a better way to get around than the bicycle. I am serious.
they invented bikesThe Wright brothers DID NOT invent "the airplane" OR bikes !They built THEIR airplane (NOT the first airplane) in 1902.
The Wright Brothers were only one group of many who were trying to invent a powered airplane, and all of them were inspired by Otto Lilienthal, a German inventor who created gliders and flew on them. (Lilienthal also helped to invent the Fatal Airplane Crash, but that is a story for another time.) Lilienthal had to take off from a hill, had to fly only as the wind allowed him to and could only fly short distances. All the airplane inventors realized that if the airplane was to be a useful tool rather than a fun toy you had to be able to go when, where and as far as you wanted...and that meant putting an engine on it.
Ballons are made of an elastic plastic while a bottle in a harder plastic
Yes they also invented the modern sled. Their mom helped them on the modern sled, but it still counts.
The world's first successful airplane with a controlled, powered and sustained heavier-than-air human flight on Dec 17, 1903.
the wright brothers were better than anyone because without them we wouldn't be flying in these big Boeing 737's
The upthrust on the balloon is greater than the weight of the balloon. Thus, it rises upwards. The upthrust on the balloon is greater than the weight of the balloon because the air inside it has a lower density than the surrounding air.
Harder to answer than you would think.If you had asked "AIRPLANE" the answer would be NOBut there have been submarines called Planes built.The little flap things on submarines are called Planes.So a Plane will work, But an Airplane designed for Air Use will not.
