## Main Question or Discussion Point

Hello, I need to know what linear acceleration and angular acceleration of head is.

This is not for physics, this is what I'm thinking, if I'm wrong please correct me and tell my why not

Shaking head-angular acceleration

Tilting head back- angular acceleration (Just in case this becomes linear, why? angle is changing right?)

Nodding your head-angular accleration

Moving your head back and forth, in a straight line- linear acceleration

Thanks
