Answer 2

$\huge \boxed{ \displaystyle \rm \orange{answer}}$

Newton's first law states that every object will remain at rest or in uniform motion in a straight line unless compelled to change its state by the action of an external force. This is normally taken as the definition of inertia. ... The amount of the change in velocity is determined by Newton's second law of motion.
