Lagrange's equations look funny at first, but they should make sense in ordinary cases. to see that this is so: (a) write down the lagrangian for a particle moving near the surface of the earth, in three dimensions, subject only to the force of gravity. (b) derive lagrange's equations of motion for this case, and show that they are the usual equations of motion you would expect.

  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.

force tends to be low and long diustance masses are high
