Question

A object p is moving with a constant velocity for 5min. Another object q is moving with changing velocity for 5 min. out of these two objects which one has acceleration? explain

Answer 1

object q has acceleration, p is moving with constant velocity which means there's no external force (force = mass * acceleration) acceleration is zero , therby velocity is constant . but in case of q velocity is changing it may be + or - according to the acceleration applied
