Define acceleration due to gravity. Derive an expression for acceleration due to gravity in terms of mass of the earth (M) and universal gravitational constant (G).
Answers
HERE IS UR ANSWER DEAR,
*The acceleration which is gained by an object because of gravitational force is called its acceleration due to gravity
* Its SI unit is m/s2.
* Acceleration due to gravity is a vector, which means it has both a magnitude and a direction.
*The acceleration due to gravity at the surface of Earth is represented by the letter g.
* It has a standard value defined as 9.80665 m/s2
*However, the actual acceleration of a body in free fall varies with location.
ACCELERATION DUE TO GRAVITY DEPRIVATION:
F= GMm/ d²--------(1)
mg=GMm/d²---------(2)
g = Where M is the mass of the earth and dis the distance between the object and the earth. For objects near or on the surface of the earth distance dis equal to the radius of the earth R.
from (1) and (2),
g= Gm/R²
hence derived...
Answer:
here is the answer
Explanation:
The acceleration due to gravity near the earth's surface is g =
The direction of this acceleration is vertically downwards, that is, towards the earth's centre.
The acceleration of a body moving near the earth's surface under the influence of gravity is the same regardless of weather it moves up, falls down or moves at some angle to the vertical
