Object having zero velocity but still accelerating

Web24 apr. 2024 · Your definition v = displacement time makes sense if the body was initially ( t = 0) at rest at a position x = 0 and you try to measure its velocity at a later time t. A more general definition would be, v = distance covered time elapsed = final position - initial position final time - initial time = x 2 − x 1 t 2 − t 1. Web2 nov. 2024 · The correct answer is have zero acceleration. Average velocity is equal to the instantaneous velocity when acceleration is zero. Important Points Average velocity The average velocity of a body is defined as the change in position or displacement divided by the time interval in which that displacement occurs. Average velocity is a vector quantity.
