Why it is necessary to has angle in radians for SHM(Simple pendulum)?
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.
if we use radians, everything is easier …
v = rω
a = rα
This implies that if we use degree it is also OK. But use of radians is more easy that degree??
no … if we use degrees …
v = 2πrω/360
a = 2πrα/360
You mean, for degree we have to use this conversion??
OK. Thanks tiny-tim :)
