Time based movement using forces

I have a setup that moves my camera that's time based. And I want to make the character's movement time based also. But the camera uses a basic " setPosition( getX+1 * frametime, getY+1 * frametime, getZ+1 * frametime ) " And the character moves using add force functions. Can I just multiply the force amount by the frametime like with the example I showed you? Thanks.
