एकसमान त्वरण से गतिमान किसी कण का वेग-समय ग्राफ कैसा होता है?
Detailed Solution & Logic
straight line inclined to time axis/ समय अक्ष पर आनत (झुकी हुई) सरल रेखा
📘 Explanation (English)
When a particle moves with uniform acceleration, its acceleration remains constant.
We know the equation of motion:
v=u+at
Where:
v = final velocity
u = initial velocity
a = uniform (constant) acceleration
t = time
This equation is of the form y = mx + c, which represents a straight line.
Therefore, the velocity–time (v–t) graph will be a straight line inclined to the time axis.
If acceleration is positive → line slopes upward.
If acceleration is negative (retardation) → line slopes downward.
🌟 Extra Facts
The slope of a velocity–time graph gives acceleration.
The area under the velocity–time graph gives displacement.
If acceleration is zero, velocity remains constant and the graph becomes a horizontal line.
This concept was clearly explained in the laws of motion given by Isaac Newton.
📗 व्याख्या
जब कोई कण समान त्वरण (Uniform Acceleration) से चलता है, तो उसका त्वरण स्थिर रहता है।
गति का समीकरण है:
v=u+at
यह समीकरण y = mx + c के समान है, जो एक सीधी रेखा (Straight Line) को दर्शाता है।
इसलिए वेग-समय (Velocity-Time) ग्राफ एक समय-अक्ष के साथ झुकी हुई सीधी रेखा होगा।
यदि त्वरण धनात्मक है → रेखा ऊपर की ओर झुकी होगी।
यदि त्वरण ऋणात्मक है → रेखा नीचे की ओर झुकी होगी।
🌟 अतिरिक्त तथ्य (Hindi)
वेग-समय ग्राफ की ढाल (Slope) = त्वरण
वेग-समय ग्राफ के नीचे का क्षेत्रफल (Area) = विस्थापन
यदि त्वरण शून्य हो, तो ग्राफ क्षैतिज रेखा (Horizontal Line) बनता है।
यह सिद्धांत Isaac Newton के गति नियमों पर आधारित है।
