Does time only go slower when I speed up in a linear fashion or does it still happen if I spin on a chair really really fast?

There are a few different ways to look at this:

1- Often we model objects as a single particle located at the center of mass. For relativity problems we then generally model this particle as traveling in a straight line. From this standpoint, you wouldn't see any time dilation due to spinning.

2- Slightly more realistically, we can look at your body as a collection of particles. Now when you spin, each particle will have a certain linear speed at any given moment. The farther away from your axis of rotation, the faster the linear speed is. In this sense you could technically find a difference in time dilation at a point close to the axis of rotation and a point farther out.

3- Most realistically, there is an absurdly small difference in distance between the inner and outer portions of your body when compared to the numbers we're dealing with in relativity. The difference in time dilation is going to be negligible.

I hope that helps! (Point it out if you think I've missed something.)
