Angle for SHM(Simple pendulum)

  1. Hi!

    Why it is necessary to has angle in radians for SHM(Simple pendulum)?

    hi shayaan_musta! :smile:

    because everything works in radians

    in particular, v = rω only works in radians
     
  4. Thanks for reply.
    But sorry for your answer.

    I need a explanation that why don't we use degree instead of radians??

    Why physicist agree to use radians particularly.

    if we use radians, everything is easier …

    v = rω

    a = rα

    etc
     
  6. This implies that if we use degree it is also OK. But use of radians is more easy that degree??
    Right?

    no … if we use degrees

    v = 2πrω/360

    a = 2πrα/360 :wink:
     
  8. You mean, for degree we have to use this conversion??
