Can a circular motion trajectory be in a straight line?

I know this might be a dumb question, but I've had to plot the trajectory of a particle undergoing circular motion, when the initial velocity was greater than zero and my trajectory plot was a straight line...
Does this mean a force is acting on the particle? Or have I done it wrong
If a particular is undergoing circular motion, it must, at all points, have a result force pointing towards the centre of the circle.

I am not sure if this answers you question, but I hope it helps.

I think I am more dumb that I don't really understand what are you doing or have done. :smile:

Perhaps, you want to post the actual question that you are solving and the work that you have done.
If an object is undergoing circular motion, shouldn't the path be circular? Is it undergoing "partial" circular motion?
