Mass/Energy Notes

Conservation Of
Mass and Energy -

Mass (kg) to Energy (J)

c - speed of light =
3.00 x 10⁸ m/s

Einstein talks
about E = mc²

Nuclear Fireball

A neutron splits a uranium nuclei.
What is this nuclear reaction called?

wpclipart.com

Fission - splitting of a large nuclei into 2 or nuclei

www.wpclipart.com

Ex) ***Energy that can be obtained from converting 2.0 Kg to energy?

E = 2.0 Kg(3.00 x 10⁸ m/s)²

 E = 1.8 x 10¹⁷ Joules

(Mass/Energy Relationship)

Typical Regents Question ...

Ex) How much energy can be generated when 2 universal mass units are completely converted into energy?

1 universal mass unit = 931 MeV

Answer: 1862 MeV
(each universal mass unit
 converted produces 931 MeV)

Author - "Fusion, which occurs when atomic nuclei combine to form new elements, is extremely powerful. All the stars in the universe, including the Sun, are nuclear furnaces fueled by fusion. Through fusion, stars are responsible for forming all the naturally occurring elements heavier than hydrogen and helium -- before stellar nucleosynthesis, only the lightest elements existed in the universe. This video segment adapted from NOVA illustrates the critical role that stars play in creating the elements."
