The force that attracts any two pieces of matter in the universe is called the gravitational force.
<h3>What is gravitational force?</h3>
Corresponds to the mutual interaction between two bodies in space, being attractive and not repulsive, allowing the translational movement of the earth and the movement of planets in orbit around the sun.
Therefore, the gravitational force was proposed by Isaac Newton, in an episode in which the physicist observed an apple falling from a tree, identifying the way in which gravity causes objects to be attracted to the center of the earth.

Answer: In Medieval Europe, knights pledged loyalty to vassals, who in turn pledged theirs to powerful lords, and serfs labored in the fields.
Explanation:
A rigid hierarchy refers to one where people who are born into a certain position in life, find it quite hard to move from it or rather one where there are different social classes and people had to be classified in one class for the system to work.
The system during medieval times was much like this. Social classes existed that determined a person's worth in society such as the knights, vassals, Lords and Royals. There was also the serfs who were considered the lowest in the hierarchy.
