Question

A meteor moving through outer space continues to move on the same path until an outside force acts on it

Answer 1

Newton stated 3 laws that rules moving bodies:

First law - an object remains in its state (resting or moving at constant speed) unless acted upon a force

Second law - the force (F) of an object is equal to its mass (m) multiplied by its acceleration (a); F = m x a

Third law - when an object exerts a force upon another, the second object exerts a force that is equal in magnitude and opposite in direction

So, according to the First Law of Motion, the metor moving through outer space will continues its motion until an outside force acts upon it

Answer 2

Answer : Inertia

(although there aren't any options this is the answer.)
