- Weightlessness experienced in a spaceship is due to :
Verified Answer
A. Absence of inertia / जड़त्व की अनुपस्थिति
B. Absence of gravity/गुरुत्वाकर्षण बल की अनुपस्थिति
C. Absence of accelerating force / त्वरण शक्ति की अनुपस्थिति
D. Free fall of the spaceship / अन्तरिक्ष यान से स्वतंत्र रूप से गिरना
Explanation:
Weightlessness experienced in a spaceship (e.g., the International Space Station) is due to the continuous state of free fall. The spaceship and everything inside it are constantly falling around the Earth in orbit. Gravity is still present, but since everything is accelerating downwards at the same rate, there is no normal force, leading to the sensation of weightlessness. Inertia is a fundamental property of matter and is always present.
