Momentum
The magnitude of a buoyant force on a balloon depends on the size of the balloon. In other words, the force will be either big or small depending on the correlating size of the balloon in use with the experiment.
The balloon is electrified by transferring elect rons from/to your hair. This electrified balloon then attracts electrons on the wall and this attraction force causes the balloon to stick to the wall until the charges decay form leakage to the wall or air.
The force in an inflated balloon is exerted outward equally in all directions.
This is because there is always the same amount of air inside the balloon, providing the same amount of outwards force. Here on the ground, that outwards force is balanced by the air outside the balloon pushing on it. Higher in the atmosphere, however, there is less air, and therefore less force. Thus as the balloon ascends, there is a greater force pushing out than pushing in, and the balloon bursts.

Erm.. no.. i believe its Buoyancy... this force causes u the hot air balloon to rise.. not Gravity..

A balloon powered car is moves because the balloon pushes out air. Whenever something exerts a force on something else (in other words, the balloon is exerting force on the air), then the object being pushed always exerts an equal and opposite reaction force on the object exerting force on it (in other words, the air exerts force on the balloon). Because the balloon is attached to the car, when the balloon is pushed by the air, the car is pushed. The law that for every force there is an equal and opposite reaction force is Newton's Third Law of Motion.
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.
This is because there is always the same amount of air inside the balloon, providing the same amount of outwards force. Here on the ground, that outwards force is balanced by the air outside the balloon pushing on it. Higher in the atmosphere, however, there is less air, and therefore less force. Thus as the balloon ascends, there is a greater force pushing out than pushing in, and the balloon bursts.
Yes.
Decrease the pressure of the surrounding environment. Thus, the force acting on the balloon from the outside decreases, allowing the air pressure that creates a force inside the balloon to have less of a counteracting force.
