Question

What do you understand by the term acceleration due to gravity?State its value in C.G.S as well as S.I system. When is acceleration due to gravity (i)Positive and (ii)Negative

ICSE Class 9 Physics Chapter Motion in One Dimension

Answer 1

Acceleration due to gravity: The acceleration produced in a freely falling body under gravity due to the earth's attraction is called acceleration due to gravity.
The acceleration due to gravity is denoted by g, and its average value in S.I system is 9.8m/s^2 and in C.G.S, its value is 980 cm/s^2.
g has a positive value when the body is falling towards the earth and a negative value when the body is rising vertically upward.

Answer 2

Explanation:

Acceleration due to gravity can be defined as the rate at which the velocity of a freely falling body increases. The S.I. unit of acceleration due to gravity is m/s
