I was working with my students in our basic physics lessons with momentum and velocity. One train of thought lead to another and we of course were talking about bicycles vs. cars as far as energy in these situations.

A student posed a question that was kind of interesting.

"What if all the cars right now, were taken away?"

Not that they had never been invented, but right now some how all cars would simply vanish.

So I wanted to pose to the lot of you, what do you educated cats think would happen?

I want to share some of the answers with my students.
