What else can I help you with?
When a balloon is filled with air and suddenly released it will fly around the room as the air escapes If compared to a space transportation the air is most similer to what subsystem of spacecraft?
The air in the balloon is most similar to the propulsion system of a spacecraft, which provides the thrust needed to move the spacecraft through space. Just as the air escaping the balloon propels it around the room, the propulsion system of a spacecraft releases propellant to generate thrust and propel the spacecraft through space.
What is the difference between an airship and a hot-air balloon?
A hot air balloon does not have any mean of steering and does not have permanent flotation. An airship has a permanent means of flotation (lighter than air gas bags) and a means of propulsion.
What is the thrust of an air hot balloon?
The thrust of a hot air balloon is generated by the buoyancy principle: the lighter-than-air hot air in the balloon causes it to float upwards. Hot air balloons do not have engines or propulsion systems like traditional aircraft.
Why was the airplane harder to invent than the hot air balloon?
The balloon is lighter than air.
What causes rocket propulsion?
For every action, there is an equal but opposite reaction. It you blow up a balloon and don't tie the end, the air inside the balloon is pushing against all of the balloon equally. When the untied end is released, air pushing out the back causes an equal affect of pushing on the front and the balloon moves forward. Rockets work in the same manner. Instead of air, they use combustible fuel for their force.
How is balloon propulsion similar to rocket propulsion?
Balloon propulsion and rocket propulsion both involve pushing against a fluid medium to create thrust. However, rockets use combustion of fuel to generate high-pressure gases for thrust, while balloons rely on the displacement of air by a lighter-than-air gas (like helium or hot air) to generate lift and propel the balloon.
What is compressed air propullsion?
The easiest way to describe compressed air propulsion: Blow air into a ballon (compress the air) then release the balloon. The balloon will take off (propulsion) due to the compressed air within.

What happened to the balloon when you released the rubber sheet?
When the rubber sheet is released, the balloon is pushed away due to the force generated by the stretched rubber sheet recoiling back to its original shape. This creates a propulsion force that propels the balloon in the opposite direction of the rubber sheet.
What is the difference between an airship and a hot-air balloon?
A hot air balloon does not have any mean of steering and does not have permanent flotation. An airship has a permanent means of flotation (lighter than air gas bags) and a means of propulsion.
How does a balloon powered car work and what is the explanation behind its propulsion mechanism?
A balloon-powered car works by releasing air from a balloon, which creates a force that propels the car forward. The air escaping from the balloon pushes against the car, causing it to move in the opposite direction. This is an example of Newton's third law of motion, which states that for every action, there is an equal and opposite reaction.
Why must the open end of the balloon face backwards if you want the car to move forward?
Because of Newton's law. This states that every action must have an equal and opposite reaction. Thus facing the balloon backwards when attached to the car and letting the air out causes the air mass in the balloon to be expelled BACKWARDS. The law then says that the car must be pushed FORWARDS with an equal force. This is how a space rocket works.
What is the thrust of an air hot balloon?
The thrust of a hot air balloon is generated by the buoyancy principle: the lighter-than-air hot air in the balloon causes it to float upwards. Hot air balloons do not have engines or propulsion systems like traditional aircraft.
What forces are being used in a balloon and rocket lab?
In a balloon lab, the force of air pressure within the balloon creates an upward force, allowing it to float. In a rocket lab, the force of thrust generated by the rocket engine propels the rocket upwards. Both labs demonstrate principles related to aerodynamics and propulsion.
Can you make a balloon fly without hot air or helium?
Yes, you can make a balloon fly using propellers or an electric motor to provide thrust. By attaching a propeller or motor to the balloon, you can create lift and propulsion to make it fly without the need for hot air or helium.
Why was the airplane harder to invent than the hot air balloon?
The balloon is lighter than air.
Can you steer a balloon or a dirigible?
While balloons are at the mercy of the wind and cannot be steered, dirigibles (or airships) have engines and rudders that allow for controlled navigation and steering. Dirigibles can ascend and descend by adjusting their buoyancy and use their propulsion systems to move in different directions.
