    Not a homework question - Just wondering.

    What is the real meaning of non-zero velocity compared to non-zero acceleration like i don't really understand the difference. Anyone care to explain?

    non-zero *anything* just means that *anything* is not 0. Is there something more you're asking about?

    Imagine you are on a train. If it is sitting at the station, not moving, that would be a zero velocity AND zero acceleration. The instant it takes off from the station, it will have a zero-VELOCITY, but a non-zero Acceleration. As it continues to accelerate it will have a non-zero velocity AND a non-zero acceleration. Once it reaches it's cruising speed, if there is nothing effecting the train, it will have a non-zero velocity but a ZERO ACCELERATION.

    Let me know if this helps.
