Define the $SI$ unit of force,the newton $(N)$. Define the $CGS$ unit of force,the dyne.

(N/A) $1$. The $SI$ unit of force is the newton $(N)$. One newton is defined as the force that,when applied to a body of mass $1 \ kg$,produces an acceleration of $1 \ m/s^2$ in the direction of the force. Mathematically,$1 \ N = 1 \ kg \cdot m/s^2$.
$2$. The $CGS$ unit of force is the dyne. One dyne is defined as the force that,when applied to a body of mass $1 \ g$,produces an acceleration of $1 \ cm/s^2$ in the direction of the force. Mathematically,$1 \ dyne = 1 \ g \cdot cm/s^2$.
