Buoyant Force

How does buoyant force help to keep a boat floating?

In physics, buoyancy is the upward force on an object produced by the surrounding fluid in which it is fully or partially immersed, due to the pressure difference of the fluid between the top and bottom of the object. The net upward buoyancy force is equal to the magnitude of the weight of fluid displaced by the body. This force enables the object to float or at least to seem lighter.

Buoyant force is the upward force exerted by a liquid on an object immersed in. Or floating on the liquid. This gives an force on the boat to keep it floating.

Buoyancy is the upward force on an object produced by the surounding fluid in which it is fully or partially immersed in. The fluid exerts this force because of the difference in the pressure from the top of the fluid to the botom of the boat in the fluid.

Bouyancy is the upwards force on an object produced by the surrounding fluid in which it is fully or partially immersed, due to the pressrue difference of the fluid b/t the top of the object and the bottom of the object. It keeps a boat floating b/c it makes the seem lighter.
