Answer:
FALSE
Explanation:
As we know that the model train is moving in circular path
so here at all point of its motion the speed is constant in terms of the magnitude only
While the direction of motion of train is changing continuously
So here we can say that the velocity is a vector quantity which shows magnitude and direction both
since the magnitude is constant but the direction is not constant while it charges continuously
So here we can say that velocity is not constant when train is moving in circular path
