Question

SI unit of force is__________.

Answer 1

Solution:

1. Force is the pull or push action that causes change in state of the body.
2. $\mathrm{Force}=\mathrm{mass}\times \mathrm{accleration}$
3. SI unit of force is newton $(\mathrm{N})$.
4. $1\mathrm{N}=1\mathrm{kg}\times 1\raisebox{1ex}{$\mathrm{m}$}\!\left/ \!\raisebox{-1ex}{${\mathrm{s}}^2$}\right.$
5. C.G.S unit of force is dyne.
6. $1\mathrm{dyne}=1\mathrm{g}\times 1\raisebox{1ex}{$\mathrm{cm}$}\!\left/ \!\raisebox{-1ex}{${\mathrm{s}}^2$}\right.$.

Thus, SI unit of force is newton.
