What is second law of netwons

Explanation:

Newton's second law says that when a constant force acts on a massive body, it causes it to accelerate.

Explanation:

Newtons second law of motion is,

                       F  =   ma

or force is equal to mass times acceleration.

  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.
