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 (18651925)
“Long before Einstein told us that matter is energy, Machiavelli and Hobbes and other modern political philosophers defined man as a lump of matter whose most politically relevant attribute is a form of energy called self-interestedness. This was not a portrait of man warts and all. It was all wart.”
—George F. Will (b. 1941)
“I am as content to die for Gods eternal truth on the scaffold as in any other way.”
—John Brown (18001859)
