PHIL 130 Lecture 14: PHIL 130 - Lecture 14 (2)

Length contraction only occurs along a line parallel to the motion. Directions of fact and do not need to be proven (for this exam). A cube of proper edge length b is oriented with its edges parallel to the x,y. and z= axes. It moves past you with velocity v = vj (parallel to the y axis). (a) find both the proper volume V0 and the volume you observe V for the cube. Now the cube moves past you with velocity (along the body diagonal). Find the volume you observe Describe the shapes of the 'cube' you observe in parts (a)and (b).
