What would happen to a moving object if friction were absent?
the object would need no force to remain in motion, so it would move in the same direction forever

A massive ball is suspended on a string and slowly pulled by another string attached to it from below.
Is the string tension greater in the upper or the lower string?
Upper string because it supports the weight of the ball in addition to your pull. The lower string supports only your pull.
