In a v–t graph for uniform acceleration,
In a v–t graph for uniform acceleration, which of the following is NOT correct?
एकसमान त्वरण के लिए v – t ग्राफ में, निम्नलिखित में से कौन – सा विकल्प सही नहीं हैं?
Detailed Solution & Logic
The v–t graph is always curved./ v–t ग्राफ सदैव वक्रित होता हैं।
📘 Explanation
For uniform acceleration, velocity changes at a constant rate with time.
In a velocity–time (v–t) graph:
-
The graph is a straight line, not a curve.
-
The slope of the graph represents acceleration.
-
Since acceleration is constant, the slope remains constant.
-
A positive slope shows positive acceleration.
-
The area under the graph gives displacement.
👉 Therefore, saying that the v–t graph is always curved is incorrect.
📗 व्याख्या
एकसमान त्वरण में वेग समय के साथ समान दर से बदलता है।
वेग–समय (v–t) ग्राफ में:
-
ग्राफ सीधी रेखा होता है, वक्र नहीं।
-
ग्राफ की प्रवणता = त्वरण।
-
त्वरण नियत होने पर प्रवणता भी नियत रहती है।
-
धनात्मक प्रवणता ⇒ धनात्मक त्वरण।
-
ग्राफ के नीचे का क्षेत्रफल ⇒ विस्थापन देता है।
👉 इसलिए “v–t ग्राफ सदैव वक्रित होता है” कथन गलत है।
⭐ Extra Facts / अतिरिक्त तथ्य
🔹 English
-
Horizontal line in v–t graph → zero acceleration.
-
Steeper slope → greater acceleration.
🔹 Hindi
-
v–t ग्राफ में क्षैतिज रेखा ⇒ शून्य त्वरण।
-
अधिक ढाल ⇒ अधिक त्वरण।
