I'm actually not sure what I did, but after reading what you wrote and doing a bit of asking around, I finally have the answer. Thank you for your help! Much appreciated!
why is distance on the x axis?
well, if i use the area under the graph, then it'd be
distance x force / 2
.06 x 12 / 2
.36 J
But can someone explain why? Since i had come up with 1.12 J when adding them all together, and .48 J when using the interval method
