The speed-time graph for a particle moving at constant speed is a straight-line ________ to the time axis.
Inclined
Aligned
Perpendicular
Parallel
The speed-time graph for a particle moving at constant speed 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.
If the speed-time graph is a straight line parallel to the time axis, then the body is
