 P: 184 Hi! Why it is necessary to has angle in radians for SHM(Simple pendulum)?
 Sci Advisor HW Helper Thanks P: 26,157 hi shayaan_musta! because everything works in radians in particular, v = rω only works in radians

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

Why physicist agree to use radians particularly.

 Sci Advisor HW Helper Thanks P: 26,157 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?
 Sci Advisor HW Helper Thanks P: 26,157 no … if we use degrees … v = 2πrω/360 a = 2πrα/360

You mean, for degree we have to use this conversion??
 Sci Advisor HW Helper Thanks P: 26,157 yup!

 Quote by tiny-tim yup!
OK. Thanks tiny-tim :)
