Write down an equation that defines pressure.

What is the SI unit of pressure$?$

Which exerts a greater pressure, a force of $100\mathrm{N}$ acting on $1.0c{m}^2$, or the same force acting on $2.0 m^2?$

What pressure is exerted by a force of $40000\mathrm{N}$ acting on $2.0m^2?$

A swimming pool has a level, horizontal, bottom of area $10.0m$ by $4.0m.$ If the pressure of the water on the bottom is $15000 Pa,$ what total force does the water exert on the bottom of the pool$?$
