Today, I am good.
Today I learnt about social justice. In my opinion, justice should be unbiased, whether is for the better or worse. It should also be unbiased to a person's prestige or background. However, there are always people with defective traits or incapability. Hence, engineers should find ways to uphold social justice by designing equipment, appliances, or tools to help.
Energy can be explained as something invisible. every object has energy, but it can change as it does work. energy has the capability to do work. F=ma, which means that an action has a reaction. Derivative of work is a change of work from one state to the other and can be expressed in the equation U = Q + W, which are:
U= Change in internal energy
Q= Heat added to system
W= work (- work done by system, + work done to system)
This means that every object, system, etc. has energy that can be lost or gained.

As the class ended, we are tasked in understanding OpenModelica simulator. In order to do that, we will have to watch tutorials of it.

The tutorials I found in youtube are as bellow.
Openmodelica is a modeling language of systems containing mechanical, electrical, electronic, hydraulic, thermal, control, electric power or process-oriented subcomponents, developed by the non-profit Modelica Association. Although the languages are similar to programming languages, it focuses on a set of equations.
The interface consists of 4 pages;
Welcome, where there are the the latest news and recent files windows
Modeling, where models are created
Plotting, in a graph
Debug, to correct mistakes or errors made in the models
The left corner are libraries which stores components to build a model. Each model have four representations; icon, diagram, text, and documentation views.
