Suppose a sphere rolls without slipping on horizontal stationary ground. Now, suppose the sphere rolls onto a surface which is moving at some velocity with respect to the previous stationary ground. How will the velocity of the rolling sphere change ?
As far as I understand, energy will be conserved. But then what ? Rolling friction is negligible and can be neglected, however other forms of friction (sliding friction) may or may not be present.
If it's not clear, what I wish to know is the behaviour of a pure rolling sphere when it moves onto a moving surface from a stationary one.
Thanks in advance.
