Physics sure is cool. That's why I do it every day. And I have cats. And also a family.

My son(7yo) got Gravitrax for Christmas. We have been having a blast inventing our own tracks. He wanted a 3-way race which used the flip-flop and the X.

It's nothing special but it's fun watching him build spatial reasoning and a joy to run the marbles down the tracks.

10/10 gift.

A bead is placed on a rod. The rod rotates at a constant angular rate. The bead begins at rest near, but not at, the pivot point. Here are two ways of viewing the motion of the bead. The left shows the motion of the bead from an inertial frame. The right shows the motion from the frame of the rod.
