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:
“[The] elderly and timid single gentleman in Paris ... never drove down the Champs Elysees without expecting an accident, and commonly witnessing one; or found himself in the neighborhood of an official without calculating the chances of a bomb. So long as the rates of progress held good, these bombs would double in force and number every ten years.”
—Henry Brooks Adams (1838–1918)
“Much of the modern resistance to chastity comes from men’s belief that they “own” their bodies—those vast and perilous estates, pulsating with the energy that made the worlds, in which they find themselves without their consent and from which they are ejected at the pleasure of Another!”
—C.S. (Clive Staples)
“I was not content to believe in a personal devil and serve him, in the ordinary sense of the word. I wanted to get hold of him personally and become his chief of staff.”
—Aleister Crowley (1875–1947)
