Conservation Of - Mass and Energy
Matter canít be
... but can be
according to the formula ...
Mass Energy (J)
c - speed of light = 3.00 x 10 8 m/s
Listen to Einstein talk about E = mc 2
A neutron splits a uranium nuclei.
What is this nuclear reaction called?
Fission - splitting of a large nuclei into 2 or nuclei
***Energy that can be obtained from converting 2.0 Kg to
E = 2.0 Kg(3.00 x 10 8 m/s) 2
E = 1.8 x 10 17 Joules
To convert universal mass units to
energy in MeV
(universal mass unit)
9.31 x 10 2
(p. 1 Reference)
Typical Regents Question ...
Ex) How much energy can be
generated when 2 universal mass units are completely converted into
1 universal mass unit = 931 MeV
Answer: 1862 MeV
(each universal mass unit
converted produces 931 MeV)
The Elements: Forged in Stars
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
