Units & Measurements is a fundamental physics topic for the NEET Examination. This topic is also called “Physical World & Measurements” in some textbooks. It is usually the first topic taught in Class 11 Physics. This topic is also one of the easiest topics for NEET Physics.
Weightage & Importance
You can expect 2 or 3 questions from Units & measurements in the NEET Exam. However, the topic is fundamental as units & measurements are used in all topics of Physics & Physical Chemistry. Thus, this topic is one of the first topics that a NEET aspirant should study and prepare.
Syllabus & Topics
As per the NTA website, the topics under Units & Measurements are:
Physics: Scope and excitement; nature of physical laws; Physics, technology, and society.
• Need for measurement: Units of measurement; systems of units; SI units, fundamental and derived units; Length, mass, and time measurements; accuracy and precision of measuring instruments; errors in measurement; significant figures.
• Dimensions of physical quantities, dimensional analysis, and its applications.
How to study Units & Measurements?
Let us simplify and organise the above topics to understand how to prepare this chapter for NEET.
Here is a simplified view of the topics:
Theory Topics:
- Introduction to Physics, Science & Technology
- Units & Measurements Basics: SI Units, Fundamental & Derived Units, Length, Mass, Time measurements
- Measurements: Accuracy & Precision, Errors in Measurements, Significant Figures
- Dimensional Analysis
Numerical Questions:
- Significant Figures
- Error in Measurements
- Dimensional Analysis
The Theory topics can be studied easily through the NCERT textbook (ebook available online) alone. Once you have studied and understood theory topics, you can move to numerical questions. For the NEET Examination, numerical questions are very important and most likely numerical questions will be asked in the NEET Examination.
The numerical topics are not very difficult and can be studied using our free online learning tools. Click on the links above to access these tools.
