Phrases such as "I burned the energy in the ice cream by jogging", or "the car is out of energy" are motivated largely by the origins of the word in physics. However, the story of energy in science is, like most things, long and complicated.

That is, they can be used to describe large systems with many particles, but it is not necessary to know that the objects are made of particles to take these measurements. This makes them very useful for describing overall changes in a system. Measuring any of these is typically a simple process, since no knowledge of the system's microscopic configuration is needed.

We will also look at examples of mechanical energy converting to internal energy.

We add all kinds of mechanical interactions to the thermal interactions we treated in Chapter 1. The term term “mechanical” is typically used to imply everything other than thermal. We introduce the Intro Spring-Mass Oscillator Model in this chapter as an application of the Energy-Interaction Model. The Spring-Mass Oscillator Model will also play an important role in Chapter 3 for the particle model of matter.

The “thing” that flows can be a real fluid, electric charge, energy, or other things that diffuse – in short, any phenomenon in which the flow of something becomes constant can be understood with this approach/model, which we call the Linear Transport Model.
