Proper velocity Proper velocity In relativity, proper velocity, also known as celerity, is an alternative to velocity for measuring motion. Whereas velocity relative to an observer is distance per unit time where both distance and time are measured by the observer, proper velocity relative to an observer divides observer-measured distance by the time elapsed on the clocks of the traveling object. Proper velocity equals velocity at low speeds. Proper velocity at high speeds, moreover, retains many of the properties that velocity loses in relativity compared with Newtonian theory. For example, proper velocity equals momentum per unit mass at any speed, and therefore
Mercy Multiplied early 2008, Mercy Multiplied have attracted considerable media attention in Australia, followed by the United States and the United Kingdom, drawing criticism of their employment of unqualified staff, overall medical negligence, and the use of demonic deliverance in their approach to treatment. The company's rebranding efforts from Mercy Ministries to Mercy Multiplied, but also including the new brand A Girl Called Hope in New Zealand, were criticized as attempts to silence critics.
