# How to visualize the angular frequency in SHM?

Can anyone define how can i visualize the angular frequency(ω) in a SHM y(t)=R sin(ωt+ϕ) (where ω=2π/T).Bcoz we can visualize frequency(f=1/T) as number of times the process is repeated in 1 sec so how to define this angular frequency ω.

Also in SHM (a =–kx/m) then here why do we define k/m = ω^2

so plz tell me how to visualize the angular frequency in SHM

You can relate it to $$\omega$$ in uniform circular motion(the angular velocity) as SHM can be visualised as projection of uniform circular motion.
