My bad I meant to post back on this saying I figured it out shortly after posting, despite it being an issue for some time ha. The node from any vector called Vector Length will basically do this as well, but I did try your suggestion and you are correct. It should be common sense but I got as far as Geometry 2 in High School and I didnt pay attention in Physics in College. I have a hard time saving formulas on memory unless they apply to real life, otherwise its like I memorize them for sake of getting a good grade. But I will say Ive never used so much math and had a lot of fun with it as much as I have working on my game in UE4.
Thanks for reminding me of that formula sir
