I guess this question is a bit advanced, but I'll put it here, maybe somebody knows simple answer.
As in this tutorial, I've also created sphere, and put the chair on top of it using snapping to face and option "align rotation to target". Then I tried to do a little animation. I've put the chair on the top of the sphere at frame 0, and then rotated it 90 degrees at frame 120.
Unfortunately, in betweening is done as a linear motion. Is it possible to animate chair's movement on the top of the sphere using snapping? Thanks!
Short answer: yes!
However, it's definitely more advanced and a much bigger topic than I can cover in a couple posts. There are a couple different ways you could go about it, but first I'd suggest watching Wayne's excellent animation courses after you've finished the Fundamentals of Animation that's part of the 2.8 learning flow: Animation in Blender - CG Cookie
Edit: If you're super curious, here's how I would go about it with constraints:
