If a pendulum is experiencing SHM then:
$a$ is proportional to $-s$ (acceleration proportional to displacement)
let the proportionality constant be $\omega^2$
therefore $a = -\omega^2s$
$\omega$ represents the angular velocity of a rotating circle which paints a sine wave of the motion
My question is: can the following centripetal force formula be used to calculate the linear velocity (tangential velocity) of the pendulum which is experiencing SHM?
- $a = v^2 / r$
- $F = mv^2 / r$
where $a$ is the acceleration of SHM.
