Property of fluid. fan inside vacuum causes air pressure in machine to become less than the pressure of the air outside the machine- the outside air pressure pushes the air and dirt into the vacuum cleaner- A filter removes the dirt and releases the air.
Pressure and stress have the same units: pounds per square inch (psi) or newtons per square meter (N/m^2) also known as pascal (Pa). Pressure is a force per unit area typically used inside a fluid (liquid or gas) and is the same in all directions at a point inside the fluid. Stress is also force per unit area but is typically used inside solids. The difference is that the stress can be different in different directions inside the solid.
