2.

Pressure is the amount of force applied perpendicular to the surface of an object per unit area and the for it is p (or P). The SI unit for pressure is the pascal (Pa), equal to one newton per square metre (N/m2, or kg·m−1·s−2). Pascal is a so-called coherent derived unit in the SI with a special name and symbol.

Answer 2

Answer

1. What are the various units of force ?

❥ Force can change the shape, direction or state of motion of a body.

• The SI unit of force is called newton (N). Gravitational unit of force is called kilogram force or kgf. A kilogram force is the force with which a body of mass 1 kg is attracted towards the Earth.

2. Define pressure. What is the SI unit of pressure ?

❥ The force that is produced when you press on or against something .

❥ The force that a gas or liquid has when it is contained inside something .

• Pascal

All the best :)
