what are energy bar graphs?
Assistance needed.
Since this is not my area of expertise, I searched Google under the key words "energy bar graphs" to get these possible sources:

Within these sites, use <Find> for "energy bar graph."
In the future, you can find the information you desire more quickly, if you use appropriate key words to do your own search. Also see http://hanlib.sou.edu/searchtools/.
I hope this helps. Thanks for asking.
Energy bar graphs, also known as energy flow diagrams or energy transfer diagrams, represent the flow and transformation of energy within a system. They are commonly used in physics and other scientific fields to visually depict the various forms of energy present in a given situation.
To understand how to interpret energy bar graphs, let's consider a simple example: a roller coaster on a track. The energy of the roller coaster can be divided into different forms, such as potential energy (PE) and kinetic energy (KE).
Here's how you can create an energy bar graph for this situation:
1. Identify the energy forms present: Start by identifying the different forms of energy that exist in the system. In the case of a roller coaster, the main forms are potential energy and kinetic energy.
2. Assign a bar to each energy form: Draw a horizontal line for each energy form you identified in step 1. Each line represents the amount of energy associated with that form. For example, draw one line for potential energy (PE) and another for kinetic energy (KE).
3. Label the energy bars: Label each energy bar with the name of the corresponding energy form (e.g., PE and KE). This helps to clearly identify which form of energy each bar represents.
4. Indicate the relative amounts of energy: The length of each bar should reflect the amount of energy present in that form. If the roller coaster is at its highest point on the track, where it has the most potential energy, the PE bar would be longer than the KE bar. As the roller coaster moves downhill, the PE bar decreases while the KE bar simultaneously increases, indicating the transfer of energy between the two forms.
5. Optional: Include other relevant energy forms: Depending on the specific situation, you may also include bars for other energy forms, such as thermal energy, sound energy, or electrical energy, if applicable.
By following these steps, you can create an energy bar graph that visually displays the different forms of energy and how they change over time or within a system. This type of representation can help in analyzing and understanding energy transfers and transformations.
