## Angle for SHM(Simple pendulum)

Hi!

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

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

 Quote by tiny-tim 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?
 Blog Entries: 27 Recognitions: Gold Member Homework Help Science Advisor no … if we use degrees … v = 2πrω/360 a = 2πrα/360

 Quote by tiny-tim no … if we use degrees … v = 2πrω/360 a = 2πrα/360
You mean, for degree we have to use this conversion??

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