But does Angry Birds in Space (I keep thinking of PIGS IN SPACE) use the 1/r 2 form of the gravitational force? Really, I am not sure. If I could set up my own experiments, that would help. This would give an x- and y-components of the initial velocity with values of 17.75 m/s and 14.63 m/s.Ĭlearly, I need more data. ( as I found from a previous analysis) And what about the launch angle? From the trajectory plot in Tracker, I get a launch angle of about 39.5°. Why that value? Well, that is the launch velocity of the birds in the Earth-based game. What if I use a launch velocity of 23 m/s. Here are the two sets of data on plotted together (data from the video plus data from the numerical calculation): Of course, there is no noise in this plot - also it doesn't go to as high of a value for kinetic energy since it doesn't get as close to the moon. Not too bad, but also not the same as the Angry Birds shot.
