The SI unit of pressure is:
Pascal
Pressure is defined as force per unit area, and in SI units force is measured in newton and area in square metre, so the SI unit of pressure is newton per square metre; this derived unit is given the special name pascal (Pa) in honour of Blaise Pascal.
Watt is the SI unit of power, joule is the SI unit of work or energy and newton is the SI unit of force, so none of these represents pressure directly; only pascal does.
Hence, Pascal.
If the surface area increases for the same thrust (force), then the pressure on the surface ______.
