[SOLVED] a vs Fnet graph

Which unit goes on the y axis? acceleration or Fnet?

It depends which one your plotting on the y-axis :tongue: (sorry couldn't resist). Generally, your independent variable [the one you are measuring] would go on the y-axis and your dependant variable [the one you are controlling] would go on the x-axis.

lol So Fnet goes on the y axis because i'm measuring the newtons, right?

Yes, if you are chaging the acceleration and measuring how this affects the force then F goes on the y-axis.

See, I'm doing a lab and it asks me to graph a vs Fnet. The lab was measuring how fast a cart is pulled by different weights. And so Fnet was already given (one part of the lab, Fnet was constant, and the other part was not). I'm actually changing the weights that are pulling the cart (Fnet). Thanks for your help :)

So in your case your controlling the force and measuring the acceleration; so a goes on the y axis and F on the x-axis
