Time management is very much important in IIT JAM. The eduncle test series for IIT JAM Mathematical Statistics helped me a lot in this portion. I am very thankful to the test series I bought from eduncle.

constant speed does not always mean zero acceleration. If a particle is moving along a straight line with a constant speed then acceleration is zero.But if a particle is moving in a curved path then although the speed is constant but direction is always changing. That means velocity is changing.So there is an acceleration.
