## EJSS Circular Motion Ferris Wheel Model

this model uses the constant angular velocity to evolve the simulation

## Ordinary Differential Equation

$\frac{d \theta}{dt} = \omega$

## Position of Ferris Wheel Mass

the coordinates of the mass are spaced out by using

$x[i] = R sin(1+i) d \theta$

$y[i] = - R cos(1+i) d \theta$

$rot[i] = (1+i) d \theta$

where

$d \theta = \frac{2 \pi}{N_{1}}$
