Measurement of Length and Motion
Chapter: 9
| PART – II |
| IMPORTANT QUESTION ANSWER |
A. Answer the following Question:
(i) What is meant by oscillatory motion?
Ans: Oscillatory motion is a back-and-forth movement around a fixed point, like the swinging of a pendulum.
(ii) Give an example of periodic motion from daily life.
Ans: The swinging motion of a pendulum clock is an example of periodic motion.
(iii) How would you measure the distance between two towns?
Ans: By using kilometers and measuring through road maps or GPS.
(iv) How does an oscillating motion differ from a circular motion?
Ans: Oscillating Motion: Back-and-forth movement (e.g., a swing).
Circular Motion: Movement around a central point (e.g., the hands of a clock).
(v) What is the purpose of the International System of Units (SI)?
Ans: The SI system provides a standard for measuring physical quantities to ensure uniformity and consistency worldwide.
(vi) What is the primary difference between linear motion and oscillatory motion?
Ans: Linear motion refers to movement along a straight path, such as a car moving on a road, while oscillatory motion involves a back-and-forth movement around a fixed point, such as a pendulum swinging.
(vii) Why is the International System of Units (SI) important?
Ans: The International System of Units (SI) provides a standardized and universally accepted system for measuring physical quantities, ensuring consistency and accuracy across different regions and fields of study.
B. True or False:
1. In ancient times, people used body parts like fingers and arms to measure length.
Ans: True.
2. The International System of Units (SI) has no impact on modern-day measurements.
Ans: False. (SI system standardizes measurements globally.)
3. Plants exhibit movement through growth, such as roots growing towards water.
Ans: True.
4. The unit ‘meter’ is smaller than a kilometer.
Ans: True.
5. A moving car exhibits oscillatory motion.
Ans: False. (A moving car shows linear motion.)
