A Reminder

Newton's First Law Of Motion:



If no net force acts on a particle, then it is possible to select a set of reference frames, called inertial reference frames, observed from which the particle moves without any change in velocity.

This law is often simplified into the sentence "An object will
stay at rest or continue at a constant velocity unless acted upon by an external unbalanced force".


This means that in the absence of friction (your tires on pavement, for example) once you get your 4wd moving, the Good Lord and the Laws of Physics don't give you a glimmer of hope of stopping unless you can impart an external unbalanced force (hitting a dry patch, deeper snow, or a bridge abutment.)




Slow down.


For all you deniers out there; this one isn't just a Theory. It's the Law.

Gravity is just a theory, like evolution. So there's nothing to worry about. By the way, we Pastafarians believe that the reason things stay down on the surface of the world is because His noodly appendages are reaching down from the heavens and pushing us down. All hail the Flying Spaghetti Monster! So when do we members of the Church of the Flying Spaghetti Monster get our theory of "gravity" taught in schools alongside that *other* theory, huh? Huh?
