The SI unit of pressure is:
Pascal
Pressure is defined as force applied per unit area, so its SI unit is derived from the SI units of force (newton) and area (square metre).
One pascal equals one newton per square metre (1 Pa = 1 N/m²), named after French mathematician Blaise Pascal. Joule is the unit of energy, newton the unit of force and dyne is the CGS unit of force.
Hence, Pascal.
If the surface area increases for the same thrust (force), then the pressure on the surface ______.
