4 your classmate claims that an object moving along a frictionless surface with no air resistance will keep traveling forever. is this claim correct? a yes, because it will stay in motion unless it is acted upon by another force b yes, because gravity will keep it moving forever at the same speed c no, because it will continue to accelerate unless it is acted upon by another force d no, because it will eventually slow and come to a stop when the initial force wears off

Answer

Brief Explanations:

According to Newton's first - law of motion, an object in motion will stay in motion with a constant velocity (in a straight line) unless acted upon by an external force. In a frictionless and air - resistance - free environment, there is no force to slow down the object. Gravity acts vertically and does not affect the horizontal motion in this case. The object will not accelerate without an external force and the concept of "initial force wearing off" is incorrect as force is not something that "wears off".

Answer:

A. Yes, because it will stay in motion unless it is acted upon by another force
