The interaction which after applying on a body changes or try to change the state of rest or state of motion of a body is called force. The SI unit of force is Newton (N)
Force (F) = Mass (m) × acceleration (a)
The force per unit area is called pressure.
- The SI unit of pressure is the pascal (Pa) or N/m2.
- The metric unit of pressure is the bar.
