प्रश्न-5 शुद्धकथनानां समक्षम् आम् अशुद्ध कथनानां समक्षं न इति लिखत ।
(क) वायुः विना क्षणमपि जीवितुं न शक्यते ।​

Answer 1

Explanation:

Under gravity, acceleration is 9.8 m/s² and is denoted by g. When an object is falling freely under gravity, then the above equations would be adjusted as follows: v = u + gt. h = ut + 1/2 gt

explain motion under gravity or free fall and also write the three equation of motion of under gravity class 9 ncert

The three equation of motion viz. (iii) v2 – u2 = 2as are true for motion of objects under gravity. For free fall, value of acceleration a = g = 9.5 ms–2. If an object is just let fall from a height then in that as u = 0 and a = g = 9.8 m/s2.
