What is energy defined as in the context of scientific study?

1. The ability to create matter

2. The ability to do work or cause change

3. The measurement of temperature

4. The source of potential energy

The correct answer is: The ability to do work or cause change

In scientific study, energy is defined as the ability to do work or cause change. This encompasses a wide range of actions and interactions in the physical world. Energy is a crucial concept in various fields of science, including physics, chemistry, and biology, as it allows systems to perform work, undergo transformations, and drive processes. For example, when energy is absorbed by a substance, it may cause an increase in temperature or initiate a chemical reaction, demonstrating the capacity of energy to effect change. Similarly, in mechanics, energy enables objects to move or exert force, which is fundamental to understanding physical phenomena. While the other options touch on related concepts—the creation of matter, temperature measurement, and sources of potential energy—they do not encapsulate the broader definition of energy and its role in causing action or change. Thus, option B accurately conveys the essence of energy in scientific terms.
