NakedSquirrel Posted March 31, 2012 Share Posted March 31, 2012 Just having fun with some basics physics/math. I\'m going to plot my progress to studying Kerbal Physics and the grand project of flying to the mun using the paradigm of earth physics/kinematics. I figure I would post my blunders and mess-ups here for all to see as I try to launch my own Kerbal space program to the mun and maybe murs. (if it ever comes into existance)... or mupiter ;P[Test Flight 1] (Finding the acceleration of Kerbal Gravity)Disregarding air resistance and terminal velocity. The acceleration of Kerbal Gravity should be defined by:(dy) = (Vi)(t)+1/2(a)(t^2)For our first, second, third,.. seventh test flight... we launched a rocket with 3 external fuel tanks. Each fuel tank has a weight of 1.25kg (kerbal grams). The rocket has a thrust power of 130kN (kerbal ...New-tins?)The rocket flew ~11000km (kerbal meters) before running out of fuelThe rocket achieved an altitude of 12800km (kerbal meters) before reaching a velocity of 0(km/s) (kerbal meters per second) when the fuel tanks were ejected (stage 2). We timed the fuel tanks\' decent to be 18 seconds before they finally returned to the the ground and went kaboomWe used basic kinematics in an attempt to solve for the acceleration of Kerbal Gravity:(dy) = (Vi)(t)+1/2(a)(t^2)(28000km) = 0(18)+1/2(a)(18^2)a= (79km)/(s^2)(kerbal meters per second^2) Link to comment Share on other sites More sharing options...
Radion Posted March 31, 2012 Share Posted March 31, 2012 You\'ve really got things figured out, and I applaud you for that. However, I believe this would best be suited in the General Discussion section. Link to comment Share on other sites More sharing options...
BHD124 Posted April 1, 2012 Share Posted April 1, 2012 Hmmm, this experiment got the University of Sonno Bet thinking so they tried the experiment again by using another formula:Vf^2=Vi^2+2adData was collected by launching a small rocket and was filmed.Data collected ended up being:Vf=16.1m/sVi=47.9m/sdelta d=103mAnd by pluging all these values in they ended up with acceleration due to gravity as -9.87m/s^2With an uncertainty value of 3.3%.Sources of errors include, air resistance and terminal velocity as the experiment was conducted within the atmosphere.It would be interesting to see more experiments conducted like these.Edit: OOC: Anyone know if these are up to date?http://kerbalspaceprogram.com/~kerbalsp/wiki/index.php?title=Kerbin Link to comment Share on other sites More sharing options...
