Floating and Sinking - Density - Magic 8 Pool Ball

The pressure at a certain depth in a liquid depends on…
height of liquid above the base (∆h)
density of the liquid (𝜌) (symbol rho)
gravitational field strength (g)
∆𝒑=𝝆𝒈∆𝒉 ... or 𝒑=𝝆𝒈𝒉
A floating object experiences a greater pressure on the bottom surface than on the top surface. This creates a resultant force upwards. This force is called the upthrust. When solid objects are placed in water they will float or sink depending on the density of the solid material compared with the density of water. If the object is denser than the liquid it will sink because the weight is greater than the upthrust. If the object is less dense than the liquid the upthrust is greater than the object's weight and it will float to the surface. If the object has exactly the same density as the liquid it will stay still, neither sinking nor floating upwards. The weight is equal to the upthrust. For example, ice floats on water because it is less dense than water. Lead sinks in water because it is denser than water.
You could also work out the density of an object in water 𝒑 = m/V which allows you to work out the forces acting down and see how that balances with the upthrust created by objects trying to float.[+] Show More
