Proper time is the time interval measured by a clock that is at rest relative to the event being timed. This concept plays a crucial role in understanding the effects of relative motion, particularly in the context of how different observers perceive time differently due to their relative velocities. Proper time is the shortest time interval between two events that can occur at the same location in space, making it fundamental in discussions about relativistic kinematics and the implications of time dilation.
congrats on reading the definition of Proper time. now let's actually learn it.
