If the distance-time graph is a straight line parallel to time axis, it indicates that the object is
moving with a decreasing speed
moving
moving with an increasing speed
not moving
If the distance-time graph is a straight line parallel to time axis, it indicates that the object is not moving.
What can you say about the motion of an object whose distance time-graph is a straight line parallel to the time axis ?
For uniform motion :
(a) the distance-graph is a straight line parallel to the time axis.
(b) the speed-time graph is a straight line inclined to the time axis.
(c) the speed-time graph is a straight line parallel to the time axis.
(d) the acceleration-time graph is a straight line parallel to the time axis.
