Push Me, Pull You

Two carts are connected together on an air track with a spring. Under bright lights you can see the coupled oscillation of the carts back and forth, but under black lights you can see that the center of mass moves at a constant velocity.

thats not constant, ha. Cool Concept though.

Ahhhh but I think it is constant. It’s hard to tell but I think it is an optical illusion that makes it seem like it speeds up and slows down slightly. But I put my fingers up to block the carts and only see the light. It looked constant then. I don’t think it would be on here if it wasn’t do you?
