	Given two massless, frictionless pulleys are rotating in unison because a common belt passes over their rims, which value is the same for both pulleys: their tangential velocity or their angular velocity?

	Given two specks of dust are on a common rotating record's surface, which value is the same for both: their tangential velocity or their angular velocity?
