Because of the upward force pushing it up.

It is too strong to let gravity pull it down.

Which force allows a balloon to fly?

The force of buoyancy, which is created by the displacement of air by the balloon, allows it to fly. This force is greater than the weight of the balloon, causing it to rise.


What would be the direction of the acceleration of a balloon if the balloon were being blown westward with the net force still acting vertically upward?

The direction of acceleration would be vertically upward, since the net force is acting in that direction. The horizontal motion of the balloon being blown westward does not affect the acceleration in the vertical direction.


What happens to the weigh to balloon when it is blown up and why?

When a balloon is blown up, it becomes lighter because the air inside the balloon is less dense than the surrounding air. This causes the balloon to float or rise upward, due to the principle of buoyancy.


What happens when you stick a balloon to glass will it float?

When you stick a balloon to glass, it will not float on its own. The balloon will stick to the glass due to static electricity generated when rubbing the balloon against your hair or clothes. The balloon's ability to float is determined by the gas inside the balloon and the upward force it creates, not by sticking it to a surface.


Is a hot air balloon a balanced or unbalanced force?

A hot air balloon is balanced because the upward lift force from the hot air inside the balloon is equal and opposite to the downward force of gravity on the balloon and its contents. This balance allows the hot air balloon to float in the air.
