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

Tilting head back- angular acceleration (Just in case this becomes linear, why? angle is changing right?)
Moving your head back and forth, in a straight line- linear acceleration

Thanks

I think you have everything correct.

Most are "angular acceleration" as you call it. Most head movements are rotational similar to how you can move a spinning top without moving its point of contact with the table. This is just an approximation of course.

As you mention, it is possible to move the head forward/backward in a linear movement. It is even possible to do a bit of linear movement sideways, but that seems more restricted.

I guess some necks are stiffer than others. And it doesn't get any better by sitting in front of a desk all day doing physics!

Yes, tilting your head back is considered linear acceleration because it involves a change in velocity over time, which is the definition of acceleration.

Tilting your head back can increase or decrease linear acceleration depending on the direction and magnitude of the tilt. For example, tilting your head back while moving forward will increase linear acceleration, while tilting your head back while moving backward will decrease it.

3. Can tilting your head back cause harm due to linear acceleration?

In most cases, tilting your head back will not cause harm due to linear acceleration. However, if the tilt is sudden and forceful, it can cause discomfort or injury to the neck and spine.
