What is potential energy?

Do you believe the following explanation of both energies are explained well?

In everyday language, people often use the term "energy" to describe a feeling of vitality or enthusiasm. For example, people may say that they have "a lot of energy" when they feel energetic or active. The term "energy" is also often used to refer to sources of power, such as electricity or fuel.

Energy is the ability of a system to do work. Energy is a scalar quantity that is conserved in a closed system.

Understanding energy is critical to achieving the student learning outcome in physics, which is to develop a deep understanding of the fundamental concepts of the subject. Energy is intimately connected to the concept of work.

The similarity between the everyday and technical meanings of the term "energy" is that both refer to the capacity to do something. However, the technical definition of energy is much more precise and involves specific mathematical equations and units of measure. The everyday use of the term "energy" is often more vague and context-dependent.

What impact might the similarities and differences have on your learning of physics concepts in this course?

The similarities and differences between the everyday and technical meanings of the term "energy" might require some additional effort to connect the two meanings. However, understanding the technical definition of energy is critical to achieving a deep understanding of the fundamental concepts of physics, which is the student learning outcome of this course.

Work:

Work is the product of the force applied to an object and the distance it moves in the direction of that force. Work is a scalar quantity that is expressed in joules (J). To the general public, work often refers to labor or a job that a person does to earn a living. For example, people might say, "I'm going to work" when they go to their job.

In technical language, physicists define work as the product of the force applied to an object and the displacement it undergoes in the direction of that force. Mathematically, work is defined as W = Fd, where W is work, F is force, and d is displacement.

Work is related to the student learning outcome in this course because it is intimately tied to the concept of energy. The work-energy theorem states that the work done on an object is equal to the change in its kinetic energy. This theorem is fundamental to understanding how energy is transferred from one object to another and how it can be conserved in a closed system.

The similarities between the everyday and technical meanings and uses of the terms "energy" and "work" are that both refer to the capacity to do something. However, the technical definitions are more precise and involve specific mathematical equations and units of measure. The differences between the two are that the technical definitions are much more precise and exact, whereas the everyday meanings are often more vague and context-dependent.

The impact of the similarities and differences between the everyday and technical meanings of these terms is that it may require some additional effort to connect the two meanings. However, understanding the technical definitions of these terms is critical to achieving a deep understanding of the fundamental concepts of physics.(wk5 Eryn)
