- liquid pressure
- if u submerge an object in a liquid, it experiences liquid pressure from all directions due to the particles in the liquid
- this pressure increases with depth due to the weight of the column of liquid directly above the object
- liquids cant be compressed, so their density is the same anywhere
- pressure due to column of liquid =height of column*density of liquid*gravitational field strength
- you can use this equation to find the difference in pressure=difference in depth*density*gravitational field strength
- upthrust
- when pressure in a liquid increases with depth, the force pushing upwards on the bottom of the object is greater than the force pushing down
- the upthrust acting on a object is equal to the weight of fluid it has displaced.
- if the upthrust is equal to the objects weight it will float. If the upthrust is less than the objects weight it will sink
