True/false a model train traveling at a constant speed around a circular track has a constant velocity. a. true b. false

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
