you have that backward

the only way to produce an acceleration on a mass is to apply a force

per the current version of the Standard Model
there are only 4 forces all are mediated by their respective Bosons

not counting dark mass and dark energy

there are only 2 broad categories which make up the universe
Fermions which make up all the mass and Bosons which mediate all the forces

mass is a scaler property which arises from the Higgs particle which is a scaler Boson arising from a scaler field permeating the Universe, all other Bosons are gauge Bosons

gravity effective at large distances per the inverse square law, things become muddled at the ultra short distance like inside an atom, a more inclusive model is needed, only an attractive force, mediated by the not yet detected but hypothesized Graviton, strength scale wrt electro-magnetism 10exp-61

electro/magnetic also effective at large distances per the inverse square law, both attractive and repulsive, mediated by the zero mass gauge Boson called a Photon, strength scale 1


weak nuclear only effective at very short ranges, responsible for radioactive decay, mediated by massive gauge Bosons , W+, W- and Z, strength scale 10exp -4

strong nuclear hold atom together, mediated by the Bosons called Gluons, strength scale x60, has asymptotic freedom, ie can never exist outside the nucleus(in the current universe, at one time immediately after the big bang everything was like the nucleus ie a quark-gluon soup)
