Physicst Proves That R2D2 Is Lighter Than Styrofoam
A physicist carefully examined the way R2D2 flies in Attack of the Clones, and has come to a startling discovery. Examining the thrust of R2’s flight, then adding in gravity and resistance, he discerned that R2’s mass is 100 grams.
Rhett Alain, a physicist at Southeastern Louisiana University, first turns R2’s flight into a free body diagram, pictured here. Then he solves for F-thrust, assuming Earth gravity and some atmospheric resistance (you can see all his equations here). Then he reaches the fun part, which is figuring out R2’s mass. [io9]
