Hey I need some help on this. What are 'rods' and 'clocks'. Someone told me it's a coordinate system. I don't understand it. Any help?
meter or seconds

A “rod” is just a ruler. A “clock” is an instrument that measures elapsed time. See http://www.everythingimportant.org/relativity to understand how rods and clocks are used to comprehend spacetime.Originally posted by Sul

Rods in relativity refer to physical objects used to measure distances in the theory of special relativity. They are typically represented as long, thin objects that can be moved and compared to other rods to determine the length of an object or distance between two points.
Clocks in relativity refer to devices used to measure time in the theory of special relativity. They are typically represented as a mechanism with a constant rate of motion, such as a pendulum or the vibration of atoms, that can be compared to other clocks to determine the duration of an event or the passage of time.
Rods and clocks are related in relativity because both are used to measure physical quantities, specifically distance and time, which are relative to the observer's frame of reference. The measurements made by rods and clocks are used to calculate the effects of time dilation and length contraction in special relativity.
Rods and clocks are important in relativity because they provide a way to measure the effects of time and distance in different reference frames. They allow for the calculation of relativistic effects, such as time dilation and length contraction, which are crucial for understanding the theory of special relativity and its implications for our understanding of space and time.
No, rods and clocks can only be used to measure time and distance in situations where the effects of relativity are significant. In everyday life, the effects of relativity are negligible and traditional methods of measurement are sufficient. However, in extreme situations, such as near the speed of light or in strong gravitational fields, rods and clocks must be used to accurately measure time and distance.
