Pressure exerted by a liquid increases with depth.

Pressure (P) = density (ρ) × depth (h) × acceleration due to gravity (g)

The deeper you go in a liquid, the greater the pressure becomes.

Denser liquids exert more pressure at a given depth.

Pressure is usually measured in Pascals (Pa).

Pressure exerted by any fluid, whether liquid or gas.

An upward buoyant force acts on an object submerged in a fluid.

Upward force exerted on an object immersed in a fluid.

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

An object floats when the buoyant force is greater than its weight.

An object sinks when its weight is greater than the buoyant force.

F = Ahρg, where F is the buoyant force, A is the area, h is the height, ρ is the fluid's density, and g is the acceleration due to gravity.

If an object's weight is greater than the buoyant force, it sinks; if they are equal, it floats; if the buoyant force is greater, it floats.

The fraction of an object that's submerged in a fluid, reflecting the relationship between the object's and fluid's densities.

An object floats if its density is less than the density of the fluid it is in; it sinks if its density is greater.

The amount of energy transferred when an object is moved a certain distance by a force in the direction of the motion.

The energy an object has due to its motion.

Joule (J)

Kinetic Energy = 1/2 × mass × velocity²

Work done on an object is equal to the change in its kinetic energy.

A push or pull that can change the motion of an object.

The mass of a substance per unit volume.

The ratio of the density of a substance to the density of a reference substance (usually water).
