# Simple Harmonic motion help watch

1. I'm struggling to understand the equations around SHM for M3.

What does n stand for in the equation for the period, T ?

T= 2π/n.

Thanks
2. The equation is usually written as T= 2π/ω
That is, with ω not n
ω is a constant of the motion.
The usual significance of ω is that it equals the angular velocity of the circular motion that is used to represent SHM.
If a point moves round a circle at angular velocity ω radians per second, and there are 2π radians (360 deg) in one complete circle, then it will take a time of 2π/ω to complete the circle. [Time is distance divided by speed] The time to complete one complete revolution is T, the period of the motion.

oh so the n is the same as the ω, the angular velocity in objects that go at a constant speed around the circle (that we learn in M2).

Thanks alot - i think i understand now
