Curiosity Class 7 Science Chapter 8 Measurement of Time and Motion Assertion Reason Questions

Reading Time: 7 minutes

Hello students, we are providing assertion reason questions for class 7 science (Curiosity). Assertion reason questions are the new question format that is introduced in CBSE board. The resources for assertion reason questions are very less. So, to help students we have created chapterwise assertion reason questions for class 7 science. In this article, you will find assertion reason questions for CBSE Class 7 Science Chapter 8 Measurement of Time and Motion.

The NCERT Curiosity Science textbook for Class 7, developed as per the latest National Education Policy (NEP) 2020, is a fresh and engaging resource for young learners. Titled “Curiosity: Textbook of Science for Grade 7”, this new Class 7 Science book includes 12 thoughtfully designed chapters. Each chapter encourages students to explore real-world scientific concepts, develop critical thinking, and spark curiosity through hands-on experiences and relatable content. With its learner-centric approach, the Curiosity textbook aims to connect students with the world around them and inspire a lifelong love for science.

Assertion Reason Questions on Measurement of Time and Motion

Assertion Reason Questions

Q1. Assertion (A): The time taken by a simple pendulum to complete one oscillation is called its time period.
Reason (R): The time period of a pendulum depends on the mass of the bob.

Options:
(a) Both A and R are true, and R is the correct explanation of A.
(b) Both A and R are true, but R is not the correct explanation of A.
(c) A is true, but R is false.
(d) A is false, and R is also false.

Answer: (c) A is true, but R is false.
Explanation: The time period of a pendulum depends on its length, not the mass of the bob.

Difficulty Level: Moderate

Q2. Assertion (A): Heat energy from the Sun reaches the Earth by conduction through space.
Reason (R): Conduction requires no medium for heat transfer.

Options:
(a) Both A and R are true, and R is the correct explanation of A.
(b) Both A and R are true, but R is not the correct explanation of A.
(c) A is true, but R is false.
(d) A is false, and R is also false.

Answer: (d) A is false, and R is also false.
Explanation: Sun’s heat reaches Earth by radiation, not conduction, and conduction requires a medium.

Difficulty Level: Tough

Q3. Assertion (A): In uniform linear motion, an object covers equal distances in equal intervals of time.
Reason (R): A vehicle moving in city traffic is an example of uniform linear motion.

Options:
(a) Both A and R are true, and R is the correct explanation of A.
(b) Both A and R are true, but R is not the correct explanation of A.
(c) A is true, but R is false.
(d) A is false, and R is also false.

Answer: (c) A is true, but R is false.
Explanation: In city traffic, vehicles experience frequent changes in speed, showing non-uniform motion.

Difficulty Level: Moderate

Q4. Assertion (A): The speed of an object is the distance travelled divided by the time taken.
Reason (R): Speed is a measure of how fast or slow an object is moving.

Options:
(a) Both A and R are true, and R is the correct explanation of A.
(b) Both A and R are true, but R is not the correct explanation of A.
(c) A is true, but R is false.
(d) A is false, and R is also false.

Answer: (a) Both A and R are true, and R is the correct explanation of A.
Explanation: Speed defines how much distance is covered in unit time.

Difficulty Level: Moderate

Q5. Assertion (A): The SI unit of time is the minute.
Reason (R): SI units are based on standards agreed upon internationally for consistency in measurements.

Options:
(a) Both A and R are true, and R is the correct explanation of A.
(b) Both A and R are true, but R is not the correct explanation of A.
(c) A is true, but R is false.
(d) A is false, and R is also false.

Answer: (c) A is false, and R is true.
Explanation: The SI unit of time is the second (s), not the minute.

Difficulty Level: Moderate to Tough

Frequently Asked Questions (FAQs) on Measurement of Time and Motion Assertion Reason Questions

Q1: What are Assertion-Reason questions in Class 7 Science?

A1: Assertion-Reason questions consist of two statements: an Assertion (A) and a Reason (R). Students must determine whether both statements are true and if the reason correctly explains the assertion.

Q2: How do I answer Assertion-Reason questions correctly?

A2: To answer correctly, follow these steps:
Check if both statements are true.
If both are true, see if the reason logically explains the assertion.
Use the standard answer choices (Both true with explanation, Both true without explanation, A true but R false, A false but R true).

Q3: What is the new Science textbook “Curiosity” for Grade 7 about?

A3: The new textbook “Curiosity” for Grade 7 Science introduces students to the world of scientific exploration and discovery. It focuses on fostering curiosity and encouraging students to ask questions, observe the world around them, and engage in hands-on activities to understand scientific concepts.

Q4: What is the best way to prepare for Assertion-Reason questions?

A4: Strengthen your understanding of concepts by studying NCERT books.
Focus on cause-effect relationships in science topics.
Practice Assertion-Reason questions regularly from worksheets, sample papers, and past exams.

Q5: Are there any online resources or tools available for practicing “Measurement of Time and Motion” assertion reason questions?
