A rèir an 2na Lagh Newton,

forsa = tomad x luathachadh.

Is e a tha ann an luathachadh, atharrachadh ann an luaths rè ùine.

Tomhaisear luaths le aonadan de meatairean anns an diog (m/s).

Mar sin, tomhaisear luathachadh (atharrachadh de luaths rè diog) an aonadan de (meatairean/diog)/diog (m/s/s).

'S e a tha ann an Newton:

Am forsa a dh'aobhrachas: luathachadh de 1 meatair/diog/diog, an rian na forsa, cho fàd 's a bhitheas e a gnàthadh air corp le tomad de 1 kg.

Tha an cuideam de ubhal le meall de 102 gram (1/9.8 kg) co-ionnan ri forsa de 1 Newton.

Is e a tha ann an kilonewton (kN) forsa de 1,000 N. Cleachdar an aonad seo gu tric ann an gnìomhachas togail agus le luchd-innlichidh.

Is aonad eu-cumanta a tha anns an decanewton. Comharraichte le daN tha e faisg air co-ionnan ri forsa cuideam chileagraim. Cleachdar e uairean an formulae empiriceal innleadaireachd. bu sònraichte an formulae airson bacadh mu choinneamh carbadan rathad-iarainn- a tha a measadh bacadh anns an aonad de decanewton per tonna (daN/T).
