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:
“Because relationships are a primary source of self-esteem for girls and women, daughters need to know they will not lose our love if they speak up for what they want to tell us how they feel about things. . . . Teaching girls to make specific requests, rather than being indirect and agreeable, will help them avoid the pitfalls of having to be manipulative and calculating to get what they want.”
—Jeanne Elium (20th century)
“Viewed narrowly, all life is universal hunger and an expression of energy associated with it.”
—Mary Ritter Beard (1876–1958)
“How many persons must there be who cannot worship alone since they are content with so little.”
—Margaret Fuller (1810–1850)
