प्रश्न
A student draws a distance-time graph for a moving scooter and finds that a section of the graph is horizontal line parallel to the time axis. Which of the following conclusion is correct about this section of the graph?
विकल्प
the scooter has uniform by scooter is the maximum in this section
the distance travelled by scooter is the maximum in this section
the distance travelled by scooter is the minimum in this section
the distance travelled by the scooter is zero in this section

उत्तर
If distance time graph is parallel to the time axis then the object has not travelled any distance. So, the answer is
(d) Distance travelled by the scooter is zero in this section.

A body moves along a straight road with a speed of 20 m/s and has a uniform acceleration of 5 m/s2. What will be its speed after 2 s?
The slope of the distance-time graph at any point gives______.
The area under velocity time graph represents ______.
The slope of the distance-time graph indicates the speed.
Assertion: The position-time graph of a uniform motion in one dimension of a body can have a negative slope
Reason: When the speed of the body decreases with time then, the position-time graph of the moving body has a negative slope.
