Question

Which of the following quantities has its unit as newton second?

• A. Energy
• B. Torque
• C. Momentum
• D. Angular momentum

Answer 1

The correct option is C Momentum

Dimensional formula of newton second $=[\frac{kgm}{S^2}\times S]$

$=\left[{MLT}^{-1}\right]$

Dimensional formula of momentum $=\left[{MLT}^{-1}\right]$

Hence, momentum has the unit as $Nsec$.
