Draw an arrow showing the net force of the unit in the picture.

what is the net force and net force direction?

net force:  2 N

direction: upward

Explanation:

When only one force is applied to an object, the net force applied is equal to this force. In the picture attached in the question, we can see that only one force is applied to the object, it goes in an upward direction and has a measure of 2 N.

  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.
