Question

what is force and pressure ?

Answer 1

Force is something which can cause a change in motion of an object.In modern physics it is defined as Mass x Acceleration.

When force is applied in a unit area its called pressure.

Answer 2

What is force ?

- Force is defined as a push or pull.

- It is calculated as :

  Force = Mass × Acceleration.

- It is denoted by F.

- F = kg × ms^-2

- It's SI unit is kg ms^-2 or N ( Newton ).

- It can cause motion , stop motion, change shape and size of a body , change direction of motion , etc.

What is pressure ?

- Pressure is defined as the force applied on per unit area.

- It is calculated as :-

Pressure = Force / area

- It's unit is N m^-2 or Pa ( Pascal ).

- The surface area is inversely proportional to the pressure applied.

- Force is directly proportional to the pressure applied.
