त्वरण:
- किसी वस्तु के वेग परिवर्तन की दर को त्वरण (Acceleration) कहते हैं।
- \(a = \frac{{{v_2} - {v_1}}}{{{t_2} - {t_1}}}\)
- यहाँ v2 = वस्तु का अंतिम वेग, v1 = वस्तु का प्रारंभिक वेग, t2 = अंतिम समय, और t1 = प्रारंभिक समय
- यह एक सदिश राशि है।
- इसकी दिशा, वेग परिवर्तन की दिशा (वेग के नहीं) के समान है।
गणना:
दिया गया है - u = 18 किमी/घंटा = 5 मीटर/सेकेंड, v = 36 किमी/घंटा = 10 मीटर/सेकेंड और t = 5 सेकेंड
u = 18 × 5/18 = 5 m/s and v = 36 ×5/18 = 10 m/s
जैसा कि त्वरण को इस प्रकार लिखा जाता है
\(\Rightarrow a = \frac{{{v_2} - {v_1}}}{{{t_2} - {t_1}}}\)
\(\Rightarrow a = \frac{{{10} - {5}}}{5}=1m/s^2\)
1 मीटर/सेकेंड2
