O3 can reform through the following reaction
resulting in no net loss of ozone:
O + O2
O3 is also destroyed by the following reaction,

AOS 1. Lecture 4
Basic Concepts in
Kinetic and Potential Energies
The kinetic energy (KE) of a moving
object is proportional to the square of its
KE ~ v2.
The gravitational potential energy
(GPE) of an object is proportional to it
Wien s Law
Objects emit energy at all wavelengths, but some wavelengths carry much
more energy than others.
According to Wiens Law, the wavelengths that carry most energy are
around a value that is inversely proportional to the temperature of the
