No moving parts!
Balloon is lighter than air.
The balloon is lighter than air.
I guess they had a dream of a better way to get around than the bicycle. I am serious.
the airplane will fly farther. This is due to the fact that both the airplane and the hot air balloon use fuel. Also because the hot air balloon only means of movement is wind, While an airplane use jet propulsion. This allows the airplane to travel in any direction
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.
Popping a balloon with a pin requires less force because the pin concentrates the pressure to a small area, piercing the balloon easily. Stepping on a balloon distributes your weight across a larger area, making it harder to apply enough force to pop the balloon.
Yes they also invented the modern sled. Their mom helped them on the modern sled, but it still counts.
It is an undisputed fact that modern students find it easier to plagiarize sentences from the internet than to invent them.
A needle has a small point that concentrates pressure on a small area of the balloon, making it easier to puncture the surface and burst it. In contrast, a finger has a larger surface area, distributing the force across a wider area when pressure is applied, which makes it less effective at bursting the balloon.
The world's first successful airplane with a controlled, powered and sustained heavier-than-air human flight on Dec 17, 1903.
The buoyant force of air would be greatest for a hot air balloon because it relies on the principle of buoyancy to stay aloft. The heated air inside the balloon is less dense than the surrounding air, creating a greater buoyant force to lift the balloon. A bird and an airplane rely on aerodynamic lift generated by their wings to stay airborne, rather than buoyancy.
