What is the unit measurement for force

The SI / Metric unit of force is the ' Newton '.

1 newton is the force that accelerates 1 kg of mass at the rate of 1 m/s² .

force is mass*acceleration.

we have a very small mass: 11.4*0.001 kg

if we want 0.035n of force, we need an acceleration:

0.035 = 11.4*0.001*a

a = 0.035/(11.4*0.001) m/s^2
