Question

Define and derive an expression for acceleration.​

Answer 1

Explanation:

Derive an expression for it in terms of mass of the earth and gravitation constant. ... This force of attraction exerted by the earth on a body is called force of gravity and the acceleration possessed by a body moving under the force of gravity is called acceleration due to gravity.

Answer 2

Answer:

We get, ⇒g=GM(R−d)R3. Therefore the expression of acceleration due to gravity of a body at a depth d from the surface of earth is GM(R−d)R3. Here, we can understand that the acceleration of a body due to gravity inside earth decreases as we go from the surface to the centre of earth. At centre g=0.
