स्थितिज ऊर्जा (PE): वस्तूच्या विशिष्ट स्थितीमुळे किंवा स्थानामुळे त्यात जी ऊर्जा सामावलेली असते तिला स्थितिज ऊर्जा असे म्हणतात.
\(PE = mgh\)
जेथे, m = वस्तूचे वस्तुमान, g = गुरुत्वाकर्षणामुळे होणारे त्वरण आणि h = वस्तूची उंची
गणना:
दिलेल्याप्रमाणे:
वस्तुमान (m) = 12 किलोग्रॅम
स्थितिज ऊर्जा (PE) = 600 J
गुरुत्वाकर्षणामुळे होणारे त्वरण (g) = 10 मीटर सेकंद-2
उंची (h) = ?
आपणास माहित आहे की, स्थितिज ऊर्जा = mgh
h = स्थितिज ऊर्जा /मिलीग्रॅम = 600/[12 x 10] = 5 मीटर
म्हणून, उंची (h) = 5 मीटर. म्हणून, पर्याय 1 योग्य आहे.
