Question
Why does cream collect in the middle when milk is churned up?
Solution
When milk is churned in a vessel, the milk and the cream particles experience the centripetal force. The cream particles, being lighter, experience lesser centripetal force than heavy milk particles.
Therefore, two cannot rotate in the same orbit. The cream particles follow circular path of smaller radius and hence are collected in the middle and milk particles are thrown away from axle when milk is churned.
