गतीची समीकरणे: गतीची समीकरणे एका सरळ रेषेत एकसमान त्वरणाने गतिमान वस्तूसाठी त्वरण, वेळ, अंतर, प्रारंभिक वेग आणि अंतिम वेग यांच्यातील संबंध स्थापित करतात.
समीकरणे,
v = u + at - (1)
\(s = ut + \frac{1}{2}at^2\) - (2)
v2 = u2 + 2as - (3)
v = अंतिम वेग, u = प्रारंभिक वेग, t = वेळ, a = त्वरण, s = पार केलेले अंतर.
तसेच, न्यूटनच्या गतीविषयक दुसऱ्या नियमावरून,
F = ma
m = वस्तुमान
गणना:
दिलेले आहे:
u = 0, t = 5 s, s = 10 m, F = 100 N
\(s = ut + \frac{1}{2}at^2\) वापरुन,
\(10 = 0× 5 + \frac{1}{2}a× 5^2\)
a = 0.8 m/s2
आता, F = ma
100 = m × 0.8
m = 125 kg
