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 Francesca Battistelli. Mercy Multiplied Mercy Multiplied is an international, Christian and charitable organization that offers a six-month residential program for young women aged between 13 and 28 who struggle with various "life controlling" issues such as eating disorders, depression, self-harm, abuse issues, and drug and alcohol addictions.
