In these earthquake videos, am I correct in thinking that the mass is stationary and the building is moving around it?

- rrrrrrrrrrrryan 4y agoWell, the damper isn't completely stationary, but it is moving much less than the building around it, yes. A good demonstration here: https://m.youtube.com/watch?t=607&v=VCxm3vTWgvU&feature=youtu.be https://m.youtube.com/watch?t=607&v=VCxm3vTWgvU&feature=yout...
