Caesius Posted March 29, 2013 Share Posted March 29, 2013 I am taking Calculus III for one of my classes and Im learning about solving for Tangent Vectors and Normal Vectors for a curve. I figured out a way to determine the g-force exerted on a "particle" at a particular point on the curve by using vector calculus. So, just for laughs, I wanted to find out what g-forces a particle would experiance on the curve f(x) = x2. However, in order to solve it, I need the parametric equations for f(x) = x2. Im trying to make the parametric equations work so f(x) is like a rollercoster. However, everytime I try and solve for the parametric equations, I get gravity working "upside down" and my "particle" slows down as it approaches the origin (the bottom of my "rollercoster", whereas it should be speeding up.) Can anyone help? Thanks! Link to comment Share on other sites More sharing options...
