- कोणत्याही ग्रहाच्या गुरुत्वाकर्षणामुळे कोणत्याही वस्तूने प्राप्त केलेल्या त्वरणाला त्या ग्रहाचे गुरुत्वीय त्वरण म्हणतात.
- जिथे, G = वैश्विक गुरुत्वीय स्थिरांक = 6.67 × 10-11Nm2/kg2, M = ग्रहाचे वस्तुमान, r = त्रिज्या किंवा त्या ग्रहाचे केंद्रापासूनचे अंतर.
- प्रत्येक ग्रहाचे वस्तुमान आणि त्रिज्या भिन्न असल्याने गुरुत्वीय त्वरण वेगवेगळ्या ग्रहांसाठी भिन्न असेल.
- वजन म्हणजे एखादी व्यक्ती किंवा वस्तू किती जड आहे याचे मोजमाप.
- W = mg
- जेथे, m = वस्तूचे वस्तुमान, g = त्या ग्रहाचे गुरुत्वीय त्वरण.
गणना:
पृथ्वीचे वस्तुमान M आणि त्रिज्या r मानू,
मग गुरुत्वीय त्वरण यासमान आहे,
आणि वजन, W = mg =
आता, M' ग्रहाचे वस्तुमान =
मग गुरुत्वीय त्वरण
आणि वजन, W' = mg' =
