During Luke's Yoda training, the master had a negative weight.

On a Wired blog, user Rhett Alleyn, a physicist by training, assessed the weight master Yoda, and shots the Empire Strikes Back in Episode 5 of the Star Wars saga. Worthy results of surprise he received. The blogger calculated the position center of mass, the system of Luke and Yoda on his leg organized.

Carrying out the calculations, a number of assumptions were made by Rhett Alleyn: on the planet Dagob gravity was also arranged, and on Earth like. Luke Skywalker, the young Jedi, the mass is also distributed, and the earthling as an ordinary, even if he is an alien. The blogger also suggested that neither Yoda nor Luke used force in the training course, relying only on physical strength.

The student’s weight and height were taken for 175 centimeters and 68 kilograms. A blogger used medical research data to determine the mass distribution in Luke's body.

Since Luke was in equilibrium, not deviating to the sides, his center of mass on the axis of the vertical support should have been lying, through the arm passing the supporting one. Otherwise, the moment of force and the reaction force of the support, by all the laws of physics, arises and seeks to turn the young Padawan. In total, the model has five material points, and the sixth point is the mass center of the Yoda master. On the search for the center of mass of the system the whole equation was made by a blogger.



The only unknown in the whole system is the master’s weight. It was then calculated by the physicist, and the results were amazing. Has a negative weight in the Yoda scene,he pulls the padawan up to 43.7 kilograms by force . Apparently, Yoda conducted sparing training, using force nevertheless.
