Editing Motion (section)

=== Particles ===
According to the [[laws of thermodynamics]], all [[Subatomic particle|particles]] of [[matter]] are in constant random motion as long as the [[temperature]] is above [[absolute zero]]. Thus the [[molecule]]s and [[atom]]s that make up the human body are vibrating, colliding, and moving. This motion can be detected as temperature; higher temperatures, which represent greater [[kinetic energy]] in the particles, feel warm to humans who sense the thermal energy transferring from the object being touched to their nerves. Similarly, when lower temperature objects are touched, the senses perceive the transfer of heat away from the body as a feeling of cold.<ref>[http://www.colorado.edu/UCB/AcademicAffairs/ArtsSciences/physics/PhysicsInitiative/Physics2000/bec/temperature.html Temperature and BEC.] {{webarchive|url=https://web.archive.org/web/20071110174808/http://www.colorado.edu/UCB/AcademicAffairs/ArtsSciences/physics/PhysicsInitiative/Physics2000/bec/temperature.html |date=2007-11-10 }} Physics 2000: Colorado State University Physics Department</ref>
