Actually it does. That's the whole point of the "buoyant force".
Buoyancy always acts in the direction opposite to the direction of the gravitational force. We normally consider this direction as 'upward'.
It is a force which acts in the upward direction.
The bouyant force acts in an upward direction against gravity. It keeps things from sinking.
The lift force is the force acting against the aircraft's weight. For straight and level flight, lift acts in the upward vertical direction and the weight of the aircraft acts in the downward vertical direction. For level flight, lift = weight.
That force is refereed to as the normal forces. it only applies to objects on a solid surface.
The buoyant force on an object submerged in a fluid is caused by the pressure difference between the top and bottom of the object. To overcome the gravitational force, the buoyant force acts in the upward direction. The larger pressure at greater depth pushes upward on the object.
buoyant force
it acts in an upward motion?/
The force that opposes a downward force on an object would be called the "normal force". For example, it is as a result of the normal force that people do not fall though the ground the same way that they fall through the air.
The force of gravity on the same on land and water.However, in water, there is an upward force of buoyancy which acts in an opposite direction to the force of gravity. Hence, in water, the total net force downward is lower.
When a body is immersed in water , due to pressure difference between upper surface and lower surface of the body an unbalanced upward force acts on a body . This unbalanced upward force is called Buoyancy force
Air resistance.
