What class lever is a human nodding their head in physical science?
A human nodding their head is an example of a class 1 lever, where the fulcrum is at one end, the effort is applied at the other end, and the load is in between. In this case, the neck acts as the fulcrum, the muscles in the neck provide the effort, and the head serves as the load.
Where can a first class lever be found in the body?
A first-class lever can be found in the body at the atlanto-occipital joint, where the head is balanced on top of the neck. The effort (muscle force) is applied at the back of the head when nodding forward, the fulcrum is at the joint itself, and the resistance is provided by the weight of the head.

No, tipping your head back is an example of a third-class lever. In a third-class lever, the effort force is between the fulcrum (joint) and the load (head) being moved.

The neck acts as a third-class lever, as the effort (muscle force) is applied between the fulcrum (cervical vertebrae) and the load (head). This allows for a wide range of motion but requires more effort from the muscles.
Is a axe a class 1 lever or a class 2 lever or a class 3 lever?
An axe is a class 1 lever because the fulcrum (pivot point) is between the effort (force applied by the user) and the load (object being cut). When the user applies force to the handle, the axe head exerts that force on the object being cut.
