Motion in a Straight Line MCQ questions with answers
The first 3 of 19 questions. Unlock the series for the rest, each with a solution.
Q1. Which one of the following is the odd one out among these kinematic quantities?
इन गतिकीय राशियों में से निम्नलिखित में से कौन-सी एक असंगत है?
- A. Velocity / वेग
- B. Speed / चाल
- C. Acceleration / त्वरण
- D. Displacement / विस्थापन
Solution
Displacement, velocity and acceleration are vector quantities, whereas speed is a scalar, making it the odd one out.
विस्थापन, वेग और त्वरण सदिश राशियाँ हैं, जबकि चाल एक अदिश राशि है, जिससे यह असंगत है।
Q2. Which one of the following is NOT a possible shape of the position-time graph for a particle moving with constant velocity?
स्थिर वेग से गतिमान किसी कण के लिए स्थिति-समय ग्राफ का निम्नलिखित में से कौन-सा एक संभावित आकार नहीं है?
- A. A straight line with negative slope / ऋणात्मक ढाल वाली एक सरल रेखा
- B. A straight line with positive slope / धनात्मक ढाल वाली एक सरल रेखा
- C. A straight line parallel to the time axis / समय अक्ष के समांतर एक सरल रेखा
- D. A parabola opening upward / ऊपर की ओर खुलने वाला एक परवलय
Solution
Constant velocity gives a straight-line x-t graph (positive, negative, or zero slope); a parabola corresponds to uniformly accelerated motion, so it is not possible.
स्थिर वेग एक सरल रेखीय x-t ग्राफ देता है (धनात्मक, ऋणात्मक, या शून्य ढाल); परवलय समान त्वरित गति के अनुरूप होता है, इसलिए यह संभव नहीं है।
Q3. Consider the following statements about relative velocity in one dimension: 1. The relative velocity of A with respect to B is the negative of the relative velocity of B with respect to A. 2. If two bodies move in the same direction with equal speeds, each is at rest relative to the other. 3. The relative speed of two bodies moving in opposite directions is always less than the speed of either body. Which of these statements is/are correct?
एक विमा में सापेक्ष वेग के विषय में निम्नलिखित कथनों पर विचार कीजिए: 1. A का B के सापेक्ष वेग, B के A के सापेक्ष वेग का ऋणात्मक होता है। 2. यदि दो पिंड समान दिशा में समान चालों से गतिमान हों, तो प्रत्येक दूसरे के सापेक्ष विरामावस्था में होता है। 3. विपरीत दिशाओं में गतिमान दो पिंडों की सापेक्ष चाल सदैव किसी भी एक पिंड की चाल से कम होती है। इनमें से कौन-सा/से कथन सही है/हैं?
- A. 2 and 3 only / केवल 2 और 3
- B. 1 and 3 only / केवल 1 और 3
- C. 1, 2 and 3 / 1, 2 और 3
- D. 1 and 2 only / केवल 1 और 2
Solution
Statements 1 and 2 follow directly from v(A,B) = -v(B,A) and equal velocities cancelling; statement 3 is false because for opposite directions the relative speed is the sum of the speeds, which exceeds either one.
कथन 1 और 2 सीधे v(A,B) = -v(B,A) तथा समान वेगों के निरस्त होने से निकलते हैं; कथन 3 असत्य है क्योंकि विपरीत दिशाओं के लिए सापेक्ष चाल चालों का योग होती है, जो किसी भी एक से अधिक होती है।
