SI unit of force is:
The Newton (N) = 1 kg.m/s^2. Named after Sir Isaac Newton, it measures force in the SI system.
Chapter 1 (Measurements) is one of the most important chapters in ECAT Physics. Every year, multiple questions appear from this chapter in the actual exam. Practice these solved MCQs covering SI Units, Significant Figures, Dimensional Analysis, Errors & Uncertainties to strengthen your preparation. All questions include correct answers and detailed explanations written by experts.
We have carefully curated MCQs from Chapter 1 (Measurements) following the official ECAT 2026 syllabus. Each question comes with the correct answer and detailed explanation.

The Newton (N) = 1 kg.m/s^2. Named after Sir Isaac Newton, it measures force in the SI system.
Leading zeros are not significant. 3, 4, and trailing 0 are significant = 3 sig figs. The trailing zero indicates precision.
Dimensional analysis verifies equations by checking if both sides have the same dimensions. If dimensions mismatch, the equation is wrong.
Standard Vernier caliper: 1 main scale div - 1 Vernier div = 1mm - 0.9mm = 0.1mm = 0.01cm.
Newton (kg.m/s^2) is derived from base units. The 7 SI base units are: kg, m, s, A, K, mol, cd.
Systematic errors are consistent and unidirectional. They are removed by calibration, correct techniques, and applying corrections.
Velocity = displacement/time. [L]/[T] = [LT^-1]. No mass dimension since velocity is a kinematic quantity.
Least count = smallest measurement an instrument can make. E.g., ruler with mm markings has least count of 1mm.
Nano (n) = 10^-9. Prefixes: milli=10^-3, micro=10^-6, nano=10^-9, pico=10^-12.
Random errors are unpredictable fluctuations minimized by taking multiple readings and averaging. This reduces individual random variations.

This Physics chapter is also tested in other Pakistani entry tests. Practice the same topics with exam-specific focus:
In ECAT, Physics typically has 100 total MCQs. Chapter 1 (Measurements) usually contributes 3-5 MCQs in the actual exam. On Apna MCQs, we provide 10+ practice MCQs with detailed explanations for thorough preparation.
Yes! All MCQs on Apna MCQs are updated according to the latest Various Universities ECAT 2026 syllabus. Our team of expert educators regularly reviews and adds new questions based on the latest exam patterns and past papers.
Our Measurements MCQs cover all important topics including SI Units, Significant Figures, Dimensional Analysis and more. Each topic has multiple MCQs ranging from easy to hard difficulty to ensure comprehensive preparation.
To prepare Measurements for ECAT: 1) Read the textbook thoroughly, 2) Make notes of key concepts, 3) Practice MCQs on Apna MCQs with explanations, 4) Take mock tests, 5) Review weak areas. Our chapter-wise approach ensures you cover all 15 chapters systematically.
After completing Chapter 1, move to the next chapter on Apna MCQs. We cover all 15 chapters of Physics with chapter-wise MCQs. You can also take full-length ECAT mock tests for timed practice.
Our MCQs include questions modeled on ECAT past papers as well as original questions created by subject experts. The questions cover all topics in Measurements that are part of the official ECAT syllabus.
Absolutely! While these MCQs are organized for ECAT preparation, the content covers the same Physics Chapter 1 (Measurements) topics tested in FSc/Inter board exams. Many students use Apna MCQs for both board and entry test preparation.
Yes! Apna MCQs provides free access to chapter-wise MCQs for MDCAT, ECAT, LAT, IBA, Nursing and other entry tests. We believe quality education should be accessible to every student in Pakistan.
