forces part 2 of 2
pressure is the force per unit area.
when working out the pressure of something this equation becomes handy: pressure=force/area (pressure equals force divided by area). this is measured in N/m squared or Pa.
large area of contact means there is a smaller pressure
small area of contact means there is a large area of pressure.
in liquid the pressure increases with depth. the reason this is, is because pressure is equal to density times gravity times depth.
floating occurs because the weight's…
