To design a car model that operates on chemical energy, it's essential to clarify the type of chemical energy being utilized, such as combustion or battery power. Proper communication and specific questions are crucial for receiving effective assistance in project discussions. All vehicles fundamentally rely on chemical energy, which can be harnessed in various ways. Engaging with the community in a clear and structured manner will facilitate better guidance and support. Understanding these foundational concepts is key to progressing in the project.
