if we have constant velocity when drawing a free-body diagram, it means the forces must
group of answer choices

a. be present
b. be labeled
c. cancel
d. be in the same direction

I believe the answer is A and D.

I am unsure of C.

  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.
