Velocity quantity, momentum, is a vector and defined by In special relativity, the dimensionless Lorentz factor appears frequently, and is given by where γ is the Lorentz factor and "c" is the speed of light. Escape velocity is the minimum speed a ballistic object needs to escape from a massive body such as Earth. It represents the kinetic energy that, when added to the object's gravitational potential energy, (which is always negative) is equal to zero. The general formula for the escape velocity of an object at a distance "r" from the center of a planet with mass "M" is where
Mercy Multiplied three financial principles for the program: According to the three guiding principles that founder Nancy Alcorn established, the Mercy Multiplied website states that they do not accept government funding, and as such, are supported solely by donations from individuals, organizations and other ministries. With regard to fund raising events, Mercy Multiplied host gala dinners, Christmas donation drives and running marathons throughout the year, and invite visitors to their website to donate by becoming a financial partner or "sponsoring" a girl. Mercy Multiplied also sell resources to raise funds such as books and sermons by founder Nancy Alcorn, as well as
