Proper velocity addition formula: where formula_3 is the beta factor given by formula_4. or in terms of logarithms: Proper velocity is useful for comparing the speed of objects with momentum per unit rest mass ("w") greater than lightspeed "c". The coordinate speed of such objects is generally near lightspeed, whereas proper velocity tells us how rapidly they are covering ground on "traveling-object clocks". This is important for example if, like some cosmic ray particles, the traveling objects have a finite lifetime. Proper velocity also clues us in to the object's momentum, which has no upper bound. For example, a 45 GeV electron
Mercy Multiplied 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.
