To conserve momentum. Momentum before = momentum after.Dunno get your aerolas out and swing them about , since the balloon is not initially moving (when you hold the opening shut), the momentum before is mv, v = 0 so m(0) = 0 kgm/s. After you let go of it, the air pressure escapes backwards and pushes the balloon in the opposite direction,oh my god i.e. in the forward direction (Newton's 3rd law - reaction pairs). This mean that the air escaping has negative momentum and the balloon moving forward has positive momentum

Why does balloon fly?
The hot air inside the balloon expands, making the hot air balloon fly.
How does a air balloon fly?
air is heavier than balloon, air rises

What time fly hot air balloon?
i think it takes a long time for a hot air balloon to fly
Why does hot balloons fly?
The hot air inside the balloon expands, making the hot air balloon fly.
Did the montgolfier brothers fly a hot air balloon first?
Yes they were first to fly the first hot air balloon
Where do hot air balloon fly form?
Hot air balloons can pick up and fly from just about anywhere. As long as the surface is flat a hot air balloon can fly from it.
Does a pilot fly a hot air balloon?
An aeronaut flies a hot air balloon
Did the montgolfier brothers fly the first hot air balloon or air ship?
hot air balloon
What qualifications do you need to fly a hot air balloon?
qualifying in a hot air balloon and a pilots license.
What are the advantage of a hot air balloon?
the mechanical advantage of a hot air balloon is this that we can use it in many good ways like it is for individual flight for every one, and can be use at any time but it depends on the air resistance + gravity because if the gravity is low the hot air balloon would fly far and far in the air and if the gravity is hifgh it would unable to fly and in air resistance if the air is high it would be difficult for a hot air balloon to fly and if air resistance is low it would be difficult for hot air balloon to fly in the air
How do hot air balloons use air to fly?
Hot air balloons rely on the principle that hot air rises. The burner heats up the air inside the balloon, making it less dense and causing the balloon to become buoyant. By controlling the temperature of the air inside the balloon, the pilot can control the altitude of the balloon.
