GENERAL KNOWLEDGE

Detailed explanation-1: -The value of acceleration due to gravity at Earth’s surface is 9.8 ms−2. The altitude above its surface at which the acceleration due to gravity decreases to 4.9 ms−2, is close to (Radius of earth =6.4×106 m ) No worries!

Detailed explanation-2: -g = 9.8 m/s2 This means that every second an object is in free fall, gravity will cause the velocity of the object to increase 9.8 m/s. So, after one second, the object is traveling at 9.8 m/s.

Detailed explanation-3: -Its value is 9.8 m/s2 on Earth. That is to say, the acceleration of gravity on the surface of the earth at sea level is 9.8 m/s2. When discussing the acceleration of gravity, it was mentioned that the value of g is dependent upon location. There are slight variations in the value of g about earth’s surface.

Detailed explanation-4: -"9.81 meters per second squared” means that objects on Earth will accelerate (or go faster) 9.81 meters every second, if they are in free fall, due to the pull of gravity. Throughout space, gravity actually is constant.

Detailed explanation-5: -The acceleration due to gravity on Earth or the value of g on Earth is 9.8 m/s2. This implies that, on Earth, the velocity of an object under free fall will increase by 9.8 every second. This acceleration is due to the Earth’s gravity.
