Relativistic Kill Vehicle - Calculating Energy Content

Calculating Energy Content

Newton's formula for kinetic energy, given as, is only an approximation for the kinetic energy of an object, reasonably accurate for speeds well below c, approximately 3 × 108 m s−1. For higher speeds, Einstein's formula for kinetic energy, Ek, must be used.

Where:
m is the object's mass in kg,
c is the speed of light in m s−1,
is the Lorentz factor, given by:

Where v is the velocity of the object in question.

Therefore, expanded the equation is:

Famous quotes containing the words calculating, energy and/or content:

    Sin in this country has been always said to be rather calculating than impulsive.
    Frank Moore Colby (1865–1925)

    His eloquence was of every kind, and he excelled in the argumentative as well as in the declamatory way. But his invectives were terrible, and uttered with such energy of diction, and stern dignity of action and countenance, that he intimidated those who were the most willing and the best able to encounter him. Their arms fell out of their hands, and they shrunk under the ascendant which his genius gained over theirs.
    Philip Dormer Stanhope, 4th Earl Chesterfield (1694–1773)

    Yet the New Testament treats of man and man’s so-called spiritual affairs too exclusively, and is too constantly moral and personal, to alone content me, who am not interested solely in man’s religious or moral nature, or in man even.
    Henry David Thoreau (1817–1862)
