General Science is a broad field that encompasses a wide range of topics, from the physical sciences to the life sciences. It is an essential part of the APPSC Prelims Exam, and candidates are expected to have a good understanding of the subject.

Here is a brief overview of some of the key topics in General Science:

• Physics: Physics is the study of matter and energy and their interactions. It is a fundamental science that provides the foundation for many other sciences, such as chemistry and biology. Some of the key concepts in physics include force, motion, energy, and electricity.
• Chemistry: Chemistry is the study of the composition, structure, and Properties of matter. It is a natural science that seeks to understand the fundamental laws of nature that govern the physical and chemical phenomena of our universe. Some of the key concepts in chemistry include atoms, Molecules, Elements, and compounds.
• Biology: Biology is the study of life. It is a natural science with a broad scope but has several unifying themes that tie it together as a single, coherent field. For instance, all organisms are made up of cells that process hereditary information encoded in genes, which can be transmitted to future generations. Another major theme is evolution, which explains the unity and diversity of life. Energy processing is also important to life as it provides the chemical energy to drive the biological processes that support life.
• Mathematics: Mathematics is the science of numbers, quantities, and shapes. It has been around for thousands of years, and it is used in many different fields, such as science, engineering, and business. Some of the key concepts in mathematics include numbers, variables, equations, and functions.
• Geography: Geography is the study of the Earth and its people. It is a social science that deals with the physical features of the Earth, such as Landforms, Climate, and vegetation, as well as the human activities that take place on the Earth, such as agriculture, Industry, and transportation. Some of the key concepts in geography include location, place, region, and Environment.
• History: History is the study of the past. It is a social science that deals with the recording of human events and the analysis of their causes and effects. Some of the key concepts in history include time, change, continuity, and causation.
• Polity: Polity is the study of government and politics. It is a social science that deals with the organization and operation of governments, as well as the relationships between governments and their citizens. Some of the key concepts in polity include power, authority, legitimacy, and Sovereignty.
• Economics: Economics is the study of the production, distribution, and consumption of goods and Services. It is a social science that deals with the allocation of scarce Resources among competing ends. Some of the key concepts in economics include scarcity, choice, opportunity cost, and efficiency.
• Current Affairs: Current affairs are the events that are happening in the world today. They can be political, economic, social, or environmental. It is important to stay up-to-date on current affairs because they can have a significant impact on our lives. Some of the key sources of current affairs information include newspapers, magazines, television, and the Internet.
• General Knowledge: General knowledge is a broad term that refers to a wide range of information about the world. It includes knowledge of history, geography, politics, economics, science, and culture. General knowledge is important because it helps us to understand the world around us and to make informed decisions.

These are just a few of the key topics in General Science. For more information, please consult a textbook or online resource.
