At what speed v will the length of a 1.00-m stick

Modern Physics Lecture 1: Foundations and Special Relativity Position, Time, and Rotation are all continuous symmetries (discrete symmetries such as reflection do not produce the same results as below):  Invariance in position (changing where in space you perform your experiment) proves momentum conservation  Invariance in rotation (eg. rotating your entire experiment by 90 degrees) proves conservation of angular momentum  Invariance in time (changing when in time you perform your experiment, eg. today vs. tomorrow) proves energy conservation Newtonian Mechanics:  Inertia  F=ma  The force of object 1 on object 2 is equal in magnitude to the force of object 2 on object 1  True in an inertial reference frame
