प्रश्न
What can you say about the motion of an object if its speed-time graph is a straight line parallel to the time axis?

उत्तर
The object is moving uniformly.
A straight line parallel to the time axis in a speed-time graph indicates that, with a change in time, there is no change in the speed of the object. This indicates the uniform motion of the object.

The graph given in figure is true for
If we denote speed by S, distance by D and time by T, the relationship between these quantities is ______.
The slope of the distance-time curve is steeper/greater is the ______.
Assertion: The slope of the distance-time graph of a body moving with high speed is steeper than the slope of the distance-time graph of a body with low velocity.
Reason: Slope of distance-time graph = speed of the body.
