Question

Grive reasons The units of force and pressure are called derived units. an​

Answer 1

How ??

Force:-

We know

According to newtons second law

$\boxed{\sf Force=Mass\times Acceleration}$

$\\ \sf\longmapsto Force=kgm/s^2$

We don't use it

$\\ \sf\longmapsto Force=Newton(N)$

Hence its a derived unit.

Pressure:-

$\\ \sf\longmapsto Pressure=\dfrac{Force}{Area}$

$\\ \sf\longmapsto Pressure=\dfrac{N}{m^2}$

$\\ \sf\longmapsto Pressure=Pascal(Pa)$

Hence its a derived unit
