Webb5 nov. 2024 · The time between two position points x 1 and x 2 is Δ t = t 2 − t 1. Elapsed time for an event is Δ t = t f − t 0, where t f is the final time and t 0 is the initial time. The initial time is often taken to be zero. Average velocity v ¯ is defined as displacement divided by elapsed time.
