Hi!

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

hi shayaan_musta!

because everything works in radians

in particular, v = rω only works in radians

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.

Angle for SHM(Simple pendulum)


if we use radians, everything is easier

v = rω

a = rα

etc

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

You mean, for degree we have to use this conversion??
