How do you find a Fnet vs time graph from either a position vs time graph, Velocity vs time, or Acceleration vs time. I know how to find Velocity vs time to position and vice versa. since the slope of the position graph tells you the velocity. I can find a acceleration from Velocity. Since slope of velocity gives you acceleration. But how do you do this find a Fnet vs. time graph from Velocity vs Time. What would the varaible even be on the y axis. Please help.
