1) Weight in the downward direction
2) Upthrust due to the displaced liquid
Two forces acting on a bubble as it rises through a liquid are buoyancy force, which pushes the bubble upward due to the difference in density between the bubble and the liquid, and drag force, which resist the movement of the bubble through the liquid by frictional resistance.
When a body is immersed in a liquid, the forces acting on it include buoyant force (upwards force due to displaced liquid), gravitational force (downwards force due to gravity), and drag force (resistance force due to the movement of the body through the liquid).
Surface Tension
The two opposing forces are buoyancy, which pushes the object up, and gravity, which pulls the object down. When these forces are equal, the object will float at a constant depth in the liquid.
The two forces acting on a body immersed in a liquid are buoyant force (upward direction) and gravitational force (downward direction). Buoyant force acts in the opposite direction to the gravitational force.
A bubble floats up because it is less dense than the surrounding air. The air trapped inside the bubble is lighter than the air outside, causing it to rise. Additionally, buoyancy forces in the liquid the bubble is formed in also contribute to its upward movement.

friction Also we can mention the forces acting on a sinking body in a liquid. The weight is more than the buoyant force
It's a gas that is inside a liquid (the bubble is the liquid).

The force of gravity pulling an object down and the normal force exerted by a surface pushing back against the object are typically not equal in size. Another example is the tension in a string holding an object and the weight of the object.

Gravity. When you place something on a liquid, and it is less dense than the liquid, gravity pulling down on the liquid forces the object to float.
A gas cannot easily pass through a liquid or a solid however it can be entrapped in it . If a gas bubble is formed in a liquid it moves upward and escapes out of the liquid. Gas cannot pass through a solid barrier.
The strength of the buoyancy of a bubble is in proportion to it's volume. Since a larger bubble has more volume, as a rule, it would rise more rapidly than a small one.
It is. A bubble is air closed with solid or liquid around it. So scientifically, it's a bubble!
