hot air rising (less dense air), gravity. aero dynamics dont do much
The two main forces acting on a hot air balloon are buoyant force, which lifts the balloon due to the density difference between the hot air inside the balloon and the cooler air outside, and gravity, which acts to pull the balloon downward.
The two forces acting on a hot air balloon that is floating are buoyant force, which pushes the balloon up, and gravity, which pulls the balloon down. These two forces are in equilibrium, allowing the balloon to float at a constant altitude.
In a hot air balloon ride, the main forces acting on the balloon are lift, gravity, and drag. The hot air inside the balloon is lighter than the cooler air outside, creating lift. Gravity pulls the balloon downwards, and drag opposes the balloon's forward movement through the air. Flight control is achieved by controlling the amount of hot air in the balloon.
The forces acting on a hot air balloon are lift, weight, thrust (provided by wind), and drag. Lift is generated by the heated air inside the balloon being lighter than the surrounding air, causing the balloon to rise. Weight is the force of gravity pulling the balloon downward. Thrust is the horizontal force provided by wind to move the balloon in a certain direction, and drag is the resistance the balloon encounters as it moves through the air.
what happens is when the hot airballonis unbalanced it stats moving around eventually going to fall when its balanced it stays perfect and doesn't wobble
Gravity is pulling everything down. The hot air in the balloon is less dense than the surrounding air, so the air forces it up through what is called buoyancy. Any air movement will shove the balloon in the direction that air is moving. The balloon will be carried along 'cause there's nothing to stop the air from doing that. Just think about what is happening and it will lock in. Gravity, the wind (moving air) and the conversion of chemical energy in fuel into thermal energy to heat the air in the balloon and give it lift through buoyancy. Simple and easy physics.
There are four main forces acting on a hot air balloon: gravity pulling it down, buoyancy lifting it up due to the hot air inside the balloon being less dense than the cool air outside, thrust from the burner propelling it forward, and drag from air resistance slowing it down.
When the force acting on a hot air balloon is balanced, the balloon will remain at a constant altitude. This means that the buoyant force on the balloon is equal to the gravitational force acting on it. As a result, the balloon neither rises nor descends.
A balloon hovercraft works by releasing air from the balloon to create a cushion of air that reduces friction with the surface. The lack of friction allows the hovercraft to move smoothly over the surface. The main forces acting on the hovercraft are thrust, lift, and gravity, which work together to keep it hovering.

When a balloon is blown up and released, the action force is the air rushing out of the balloon, pushing the balloon forward. The reaction force is the balloon moving in the opposite direction due to Newton's third law of motion.
