Science Buddies: "Ask an Expert"

The law of conservation of angular momentum cannot be confirmed in variable radii system.

We have been told that "it spins faster", but that is not good enough.

It does not "spin faster" enough.

A ball on a string does not accelerate like a Ferrari engine.

How can it be conserved if we cannot confirm it?

The experts at Science Buddies help students in grades K-12 with their hands-on science projects. If you are working on a hands-on science project, please provide more detail about your project so we can help. Otherwise, there are other sites on the web where your questions would be more appropriate. Thank you.
