if only one force is acting on an object does it HAVE TO be accelerating?

OpenStudy (caozeyuan):

I think so

OpenStudy (anonymous):

nope. it could be a constant force

OpenStudy (caozeyuan):

@coolsday but F=ma, if only one force is acting, F is non-zero

OpenStudy (anonymous):

ok, nevermind, I thought it said two forces. Your right.
