Question

Find the CGS unit of the following derived quantities: Give the relation of these CGS units with respect to their SI units.
(a) Velocity $[Hint:Velocity=\frac{length}{time}]$
(b) Acceleration $[Hint:Acceleration=\frac{velocity}{time}]$
(c) Momentum [Hint: Momentum= Mass $\times$ Velocity]

Answer 1

1. Unit of velocity in CGS system is cm/s and that in SI system is m/s.

$1m/s=100cm/s$

2. SI unit of acceleration$=m/s^2$

CGS unit of acceleration$=cm/s^2$

$1m/s^2=100cm/s^2$

3. SI unit of momentum$=kgm/s$

CGS unit of momentum$=gcm/s$

$1Kgm/s={10}^{5}gcm/s$
