What can you say about the motion of an object whose distance-time graph is:
$(i)$ a straight line,parallel to the time axis?
$(ii)$ a straight line passing through the origin making an angle with the time axis?
$(i)$ a straight line,parallel to the time axis?
$(ii)$ a straight line passing through the origin making an angle with the time axis?
(N/A) $(i)$ If the distance-time graph is a straight line parallel to the time axis,it means that the distance of the object from the origin does not change with time. Therefore,the object is stationary (at rest).
$(ii)$ If the distance-time graph is a straight line passing through the origin,it indicates that the object covers equal distances in equal intervals of time. Therefore,the object is in uniform motion.
