Question

Which of the following are the units of frictional force?

• A. newton/meter
• B. newton
• C. cubic meter
• D. $kg.m$$s^{-2}$

Answer 1

Answer: (B), (D)

The correct options are
B

newton

D

$kg.m$$s^{-2}$

Unit of frictional force is same as that of force, i.e. newton.

We know force $F$ = mass$\times$acceleration

Unit of mass = $kg$

Unit of acceleration = $m.s^{-2}$

So, unit of force = $kgm.s^{-2}$
