The upward force exerted by a fluid on an object.

The buoyant force on an object is equal to the weight of the fluid displaced by the object.

How heavy an object feels when submerged in a fluid, which is the true weight minus the buoyant force.

Density ($\rho$) is mass (m) per unit volume (V): $\rho = \frac{m}{V}$.

The upward force exerted by a fluid that opposes the weight of an immersed object.

The object floats.

The object sinks.

The fluid exerts an upward buoyant force on the object, equal to the weight of the displaced fluid.

Pressure increases with depth, leading to a net upward buoyant force on submerged objects.

The object experiences an apparent weight that is less than its true weight due to the buoyant force.

True Weight: The actual weight of an object ($mg$). | Apparent Weight: How heavy an object feels in a fluid ($F_g - F_b$).

Floating: Buoyant force is greater than the force of gravity ($F_b > F_g$). | Sinking: Buoyant force is less than the force of gravity ($F_b < F_g$).

Mass: The amount of matter in an object. | Density: Mass per unit volume ($\rho = \frac{m}{V}$).
