Hi, it is known that all bodies moving with a velocity will remain moving with a constant velocity unless a force is applied to a body. (according to newton's laws). But I thought about this:

F = Ma. But if we had a very very very very small object (hypothetically), we could virtually take M = 0 and F = 0, but this small object may still have an acceleration. This is probably okay, since M = 0 can only an approximation - but it does seem like it goes against the law stated above.. (that the acceleration may be somewhat independent of the force) . I just wanted to point this out and I hope someone will set me right. thanks
