No, buoyancy is not a contact force. It is a force exerted by a fluid (such as water or air) on an object immersed in it and acts in the opposite direction to gravity.
Upthrust is a contact force :)

Yes, there is a buoyant force acting on you when you are submerged in a fluid. However, whether you float or sink depends on the relationship between the buoyant force and your weight. If the buoyant force is greater than your weight, you will float; if it is less, you will sink.
Buoyant force is based upon the mass of the water displaced. Therefore, two objects will have the same buoyant force if they have the some volumes.
buoyant force
The force opposing the buoyant force is the force of gravity. Gravity pulls objects downward, creating a force that must be overcome by the buoyant force in order for an object to float in a fluid.
A buoyant force equals the weight of the fluid being displaced
The buoyant force on an object submerged in a liquid is equal to the weight of the displaced liquid. The density of the liquid affects the buoyant force as denser liquids will exert a greater buoyant force on an object compared to less dense liquids.
Gravitational force Electrostatic force Magnetic force Nuclear force Tension force Frictional force Normal force Buoyant force Air resistance force Elastic force
Buoyant force is the upward force exerted by a fluid on an object immersed in it. The buoyant force helps objects float by counteracting the force of gravity pulling the object down. Therefore, the greater the buoyant force acting on an object, the better its ability to float.
The buoyant force exerted on an object immersed in a liquid is equal to the weight of the liquid displaced by the object. The buoyant force is directly proportional to the density of the liquid. Therefore, the denser the liquid, the greater the buoyant force it exerts on the object.
