Y Velocity on the swing

The graph above is Cam’s v velocity versus time while on the swing. This graph is a very good representation of his y velocity while on this swing. As you can see it looks very similar to the position at this time that is because for the function is the derivative of the position function which makes it the opposite of the position function. For example if that was a sine function the velocity would show a similar looking cosine function. This also demonstrates a changing acceleration in the y direction while on the swing. This makes sense as well because in simple harmonic motion ion the acceleration is constantly changing because the direction is constantly changing.
