What is energy ?

In physics, energy is the quantitative quality that is transferred to a body or to a physical system. It is recognized in the execution of work as well as in the form of heat and light (from the Ancient Greek: v, enérgeia, "activity"). Energy is a preserved resource; according to the rule of conservation of energy, energy can only be transformed from one form to another and cannot be created or destroyed.

The joule is the SI's (International System of Units) unit of measurement for energy.

A moving object's kinetic energy, a potential energy stored by an object (for instance because of its position in a field), the elastic energy contained in a solid object, chemical energy linked to chemical reactions, radiant energy carried by electromagnetic radiation, and internal energy contained within a thermodynamic system are examples of common forms of energy. Energy is constantly being consumed and expended by all living things.

A historian writes a book in which she organizes the history of Europe into these units: the middle ages, the enlightenment,and the renaissance. This is an example of _____.A) point of view
B)historical inference
C)periodization
D)continuity over time​

Answers

Answer:

C. Periodization

Explanation:

The author puts the middle ages, the enlightenment and the renaissance as different units which shows different periods of time.

Final answer:

Periodization is the process by which history is divided into distinct periods, such as Middle Ages, Enlightenment, and Renaissance. It helps historians to break down vast quantities of data into manageable segments, but may vary and lead to oversimplifications.

Explanation:

When a historian organizes history into units such as the Middle Ages, the Enlightenment, and the Renaissance, it is an example of periodization. Periodization refers to a process by which historical events are grouped and divided into distinct periods. Through this process, historians are able to make sense of vast amounts of data by breaking it down into more manageable segments. For example, rather than focusing on the entirety of European history, a historian can focus on the specific time period of the Middle Ages, and study the political, social, and cultural developments that took place during that time.

These periods are not universally agreed-upon and may vary depending on the historian, the region, and the topic of study. The rationale behind this categorization is to make the study of history more organized and focused. Periodization can be controversial, however, as it can lead to oversimplifications or ignoring important events or trends that do not fit neatly into a particular period.
