## Main Question or Discussion Point

Hello!

I'm completing my IB Physics IA and after collecting my data and plotting the raw graph my graph seems to be a negative parabola.

In order to linearize it I though one had to square the x-axis data; however I simply get the same graph shape.

What am I supposed to do?

Only when I plot the following I get a straight line [y-axis data = y and x-axis data = x]:

y/x against 1/x.

Why is this? How do I linearize this graph?

Thankyou!
