Final answer:

During vaginal birth, primary powers involve uterine contractions, while secondary powers are the mother's pushing efforts to help with fetal expulsion.


Explanation:

Primary powers during vaginal birth refer to the inherent ability of the uterus to contract and push the fetus out. These contractions are responsible for initiating labor and gradually increasing in strength and frequency. On the other hand, secondary powers come from the mother's pushing efforts, including contractions of the abdominal muscles, to assist in pushing the baby through the birth canal during the second stage of labor.
