- गतीची समीकरणे वस्तूची हालचाल दर्शवण्यासाठी वापरली जातात आणि अशाप्रकारे दर्शविली जातात
V = u + at
V2 = U2 + 2as
जेथे S = विस्थापन, t = वेळ a = त्वरण, V = अंतिम वेग, U = प्रारंभिक वेग
गणना:
दिलेल्याप्रमाणे S = 70 मीटर, t = 7 सेकंद u = 0 मीटर/सेकंद
- विस्थापन, प्रारंभिक वेग आणि वेळ जोडणाऱ्या गतीचे समीकरण अ अशाप्रकारे दर्शविले जाते
दिलेली मूल्ये भरल्यानंतर वरील समीकरण तयार होते
- म्हणून, पर्याय 3 योग्य आहे.
