Question

Can someone explain how to convert between s,v,a,and delta, omega, and alpha?

Answer 1

If I'm understanding this correctly then
s=displacement
v=ds/dt=velocity
a=dv/dt=acceleration
I don't know about delta
\[\omega=angular\space\space velocity=v/r\]
\[\alpha=angular\space\space acceleration=a/r\]

Answer 2

If these variables are consistent, then I would guess that delta is your angular position but I'm used to seeing theta, not delta
