Si la energia potencial de ina pelota se debe a su interaccion gravitacional con la tierra ¿ por que hablamos entonces de la energia como si fuera algo que posee la pelota? es decir sin la precencia de la tierra no habria tal energia ¿o si?

the answer is b, have negligible mass

  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.
