Announcements Review The Twin Paradox Length Contraction Final QuestionsLength contractionL = L √0γ = L 0 1 − v 2 /c 2What are these things?L 0 (the proper length): the length interval measured in the frame of reference in which the object is at restL: the length measured in the frame of reference in which the object is movingObservationThe proper length L 0 is always greater than the contracted length LThe length of an object is largest for the observer at rest with respect to the object and smaller forobservers in motion with respect to itRelativity
