1In the displacement time graph of the race, which line shows Rohan's motion and which line shows Binay's motion?
2At the start, how far ahead of Binay was Rohan?
3During the race, after how many seconds did Binay overtake Rohan?
4Of the lines AB and CD, which line has the greater slope? What relation is there between the slope of a line and the speed of the person it belongs to?
5What is a displacement time graph? What is placed on which axis?
6What does a line parallel to the time axis on an s-t graph show? Why?
7In segment CD of the motorcycle's graph the average velocity came out as minus 10 m/s. What does the negative sign mean?
8How can we say that a straight line on an s-t graph shows uniform velocity and a curved line shows non-uniform velocity?
9The s-t line of an object passes through the points (2, 10) and (6, 30). Find the velocity of the object.
