An apple falls from a tree. An insect in the apple finds that the earth is falling towards it with an acceleration 'g'. Who exerts the force needed to accelerate the earth with this acceleration? (AS_(7))

Calculate the distance from the surface of the earth at which acceleration due to gravity is the same as below and above the earth

Write the equation of acceleration which is used for height h ltlt R_e from the surface of earth.

A particle falls towards the earth from inifinity. The velocity with which it reaches the earth is surface is

When an apple falls from a tree what happens to its gravitational potential energy just as it reaches the ground ? After it strikes the ground ? (AS_(7))

Starting from the centre of the earth having radius R, the variation of g (acceleration due to gravity) is shown by

Caliculate the acceleration of the moon towards earth’s center (AS_(1))

Gravitational acceleration increases at depth d from surface of Earth.
