Question

Y do u think it is necessary to define a separate quantity called pressure? Why is defining only force not enough....?

Answer 1

bcoz pressure is force upon area. if not define seperately then there is no difference between force & pressure it totaly wrong

Answer 2

there is a major difference between pressure and force . Pressure is the force exerted on a unit area and force is just an external effort whuch depends upon mass and acceleration of body
