Answer 1

Answer:

$hello$

Newton's First Law of Motion. A body at rest remains at rest or, if in motion, remains in motion at constant velocity unless acted on by a net external force. ... An object sliding across a table or floor slows down due to the net force of friction acting on the object.

Answer 2
