- स्थितिज ऊर्जा: स्थितिज ऊर्जा एक वस्तु के भीतर संग्रहित ऊर्जा है, जो वस्तु की स्थिति, व्यवस्था या अवस्था के कारण होती है।
- यह इसके द्वारा दी जा सकती है:
P. E. = m × g × h
जहां P = स्थितिज ऊर्जा, m = द्रव्यमान, g = गुरुत्वाकर्षण के कारण त्वरण, h = वस्तु की ऊंचाई।
गणना:
दिया हुआ है कि: निकाय का द्रव्यमान 50 kg, तय की गयी ऊँचाई 10 m, g = 10 m/s2
सूत्र:
स्थितिज ऊर्जा = द्रव्यमान × गुरुत्वाकर्षण के कारण त्वरण(g) × तय की गयी ऊँचाई
P. E. = m × g × h = 50 × 10 × 10 = 5000 जूल
तो विकल्प 2 सही है।
