Which of the following statements about average speed is INCORRECT?
Which of the following statements about average speed is INCORRECT?
औसत गति के बारे में निम्नलिखित में से कौन – सा कथन गलत हैं?
Detailed Solution & Logic
It is change in distance divided by change in velocity/ यह दूरी में परिवर्तन को वेग में परिवर्तन से विभाजित करके निकाला जाता है।
Explanation (Bilingual)
English:
-
Average speed is defined as the total distance traveled divided by the total time taken.
-
Formula:
Average speed= Total distance / Total time
-
Its SI unit is meters per second (m/s).
-
Average speed is a scalar quantity, so it does not depend on direction.
The statement “change in distance divided by change in velocity” is incorrect because that formula relates to acceleration, not average speed.
Extra fact:
-
Average speed is different from average velocity. Average velocity is displacement divided by total time and is a vector quantity.
Hindi:
-
औसत गति को परिभाषित किया जाता है कुल दूरी को कुल समय से विभाजित करके।
-
सूत्र:
औसतगति= कुल दूरी / कुल समय
-
इसका SI मात्रक मीटर प्रति सेकंड (m/s) है।
-
औसत गति सकल राशि (scalar) है, इसलिए यह गति की दिशा पर निर्भर नहीं करती।
वाक्य “दूरी में परिवर्तन को वेग में परिवर्तन से विभाजित करना” गलत है क्योंकि यह त्वरण (acceleration) के लिए उपयोग होता है, न कि औसत गति के लिए।
अतिरिक्त तथ्य:
-
औसत गति और औसत वेग (average velocity) अलग होते हैं।
-
औसत वेग = विस्थापन ÷ कुल समय, और यह एक सदिश राशि (vector) है।
