Answer to Question #173048 in Physics for Louis

Question

1- dyne force 

Answer 1

The dyne is defined as "the force required to accelerate a mass of one gram at a rate of one centimetre per second squared". An equivalent definition of the dyne is "that force which, acting for one second, will produce a change of velocity of one centimetre per second in a mass of one gram".

$$1\ dyn=1\frac{gcm}{s^2}=10^{-5}N$$
