the velocity time graph for part of a time journey is a horizontal straight line. what does this tell you about 1. the train's velocity and 2. about its acceleration?

If the velocity time graph for part of a time journey is a horizontal straight line ; then it means as time increases ,the velocity is same .Hence the velocity is uniform and there is no change in velocity which means 0 acceleration

Now
1) We can tell that train has a uniform velocity .

2)Train isnt accelerating .Hence ,Acceleration of train is zero .

Hi!

If the velocity-time graph for part of time journey is a horizontal straight line then that means that velocity is constant (uniform) , the time is increasing but velocity is neither increasing nor decreasing.


From this graph we can tell that-

1) Velocity of the train is constant.
2) Acceleration= Change in velocity/Time. As there is no change in velocity, Acceleration= 0.


Hope it helps...!!!
