"An object that is at rest will remain at rest, and an object that is moving will continue to move in a straight line with constant speed, if and only if the net force acting on the object is zero." This sentence is a statement of ___. - -Newton's First Law -A push or a pull is a(n) ___. - -Force -Tow forces that are in opposite directions, have equal magnitudes, and act on different objects are a(n) ___. - -Interaction Pair -A force exerted by any segment of a rope or string on an a...

According to Aristotle, natural motion was thought to be - -either straight up or straight down -According to Aristotle, violent motion was - -imposed motion - the result of forces that pushed or pulled. -example of violent motion - -objects in natural resting places could not be moved by themselves, they had to be pushed or pulled -if an object was moving "against its nature" then - -a force of some kind was responsible -if there were no force there would be - -no motion (except f...
