Upthrust! or Maybe Gravity !
When an object is moving in a particular direction, air resistance will be acting on the object in the opposite direction to the direction of travel.
when a body is immersed in a fluid,it experiencednan upward force called upthrust or buoyant force due to the liquid.It is this force that pushes the body up and supports it.
There is a force called upthrust coming from the water. this pushes objects upwards, making the resultant force lower, which means they seem to weigh less.

The same object is more buoyant in a denser fluid, and is more likely to float, than in a less dense one. That's why tennis balls float in water but not in air.

Water constantly pushes upwards against an object making it seem lighter.

The force of Buoyancy in water subtracts from the weight of the object in air.
It basically pushes the same amount of force in the same direction and in the same speed.
It is physical because the object doesn't chemical change . the object just pushes upward in water of liquid and gas( air) on an object placed in it.

As an object falls, it pushes air out of the way as it falls. Air is pushed up in the same direction and with the same amount of force applied known as air resistance.

It can be shown that any object that displaces its weight or more in water will float. That's called buoyancy. Clearly the weight of a given V volume of air is less than the same volume V of water. So there is a buoyancy force upward that pushes the bubbles to the surface.
