There is a counter-acting force when you try to move a ship: its own weight. Anything in motion will stay in motion unless stopped, and anything stopped will stay stopped unless something makes it move. To accelerate you've got to overcome the objects inertia, its inbuilt tendancy to stay put. And that's where f =ma comes in.

EDIT: to make it clear..

f = ma is

Force = mass time acceleration

my other equation was solving that for accleration, so
accleration = force over mass

The speed of light thing is..weird. And complicated, to say the least.

The speed of light is speed of light in a vaccum, BTW. Everything else is measured by that constant.
