Inquiring Minds
You asked:
What is the exact speed a particle can be accelerated?
We usually express the particle velocity as a fraction of the velocity of light. The formula is:
v/c = Sqrt(E^2-m^2*c^4)/E.
where E is the particle energy in GeV and m is the particle mass. Particles with 0 mass always travel at the speed... | {"url":"http://fnal.gov/pub/inquiring/questions/speedopart.html","timestamp":"2014-04-17T07:38:35Z","content_type":null,"content_length":"15349","record_id":"<urn:uuid:3cb3dc85-145b-4bcd-94ce-8163541ee1a3>","cc-path":"CC-MAIN-2014-15/segments/1397609526311.33/warc/CC-MAIN-20140416005206-00456-ip-10-147-4-33.ec2.interna... |
