When a force moves something parallel to the direction of that force, it is called translational motion. In translational motion, the object moves along a straight path without rotating or changing orientation.
Work is done when a force moves an object over a distance. Work is defined as the product of the force applied to an object and the distance over which the force is applied.
A balloon moves towards a wall due to the higher pressure of the surrounding air pushing it towards the surface. This pressure difference creates a force that causes the balloon to be drawn towards the wall.
No, a balloon floating in the air is not considered a projectile. A projectile is an object that is launched into the air and moves under the force of its own momentum and gravity, following a curved path. A balloon floating in the air is being supported by the buoyant force of the air around it.
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.

When a balloon is released, the air inside moves backward due to inertia, propelling the balloon forward in the opposite direction. The inertia of the moving air creates a force that pushes against the balloon, causing it to move in the direction of least resistance.
By using a heat burner, hte balloon pilot makes the air in the balloon lighter than normal air. Then the balloon moves upward and moves with the wind.
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.
water resistance is contact force.
Any force can be used to make something move. It is kind of the nature of forces.
