An impulse is the product of the on an object and the time during which it is applied

"Impulse" is a quantity equal to the product of the FORCE on an object and the length of time during which the force is applied.  The impulse is equal to the change in the object's momentum during that time.

  distance on the y-axis and time on the x-axis.

explanation:

the instantaneous velocity = change in position/time taken

the slope of the graph should give instantaneous velocity.

  slope of a graph = change in value of y -axis / change in values of x -axis

  comparing both the equations

    change in value of y -axis = change in position

  change in values of x -axis = time taken

so position values should be on the y axis and time values should be on the x axis.

distance on the y-axis and time on the x-axis.
