You might describe a model train track that changes from straight to
an
arc of a circle suddenly. I am sure you will get many better
responses,
however. - The Amateur
P.S. I have read a number of other responses, which I regard as
quibbling. Obviously, they are not helpful to achieve your goal.
But,
perhaps, you ought to explain that physics is not done in the real
world
- rather in a world of ideals that often closely approximates the real
world and always closely enough to be useful. In the meantime, I
would
like to see a really helpful answer to your question!
