If heavier bodies are attracted more strongly by the earth, why don’t they fall faster that the lighter bodies?

Is it possible for a body to have inertia but no weight?

The centre of mass of an extended body on the surface of the earth and its centre of gravity

If the mass of sun were ten times smaller and gravitational constant G were ten times larger in magnitudes -

The weight of a body at the poles is greater than the weight at the equator. Is it the actual weight or the apparent weight we are talking about? Does your answer depend on whether only the earth’s rotation is taken into account or the flattering of the earth’s at the poles is also taken into account?

The weight of an object is at the poles than at the equator. Is it beneficial to purchase goods at equator and sell them at the pole? Does it matter whether a spring balance is used or an equal-beam balance is used?

An astronaut inside a small spaceship orbiting around the earth cannot detect gravity. If the space station orbiting around the earth has a large size, can he hope to detect gravity?

Supposing Newton’s law of gravitation for gravitation forces F₁ and F₂ between two masses m₁ and m₂ at positions r₁ and r₂ read F₁ = - F₂ = GM₀² r where M₀ is a constant of dimension of mass, r₁₂ = r₁ – r₂ and n is a number. In such a case,

A person sitting in a chair in a satellite feels weightless because

A body is suspended from a spring balance kept in a satellite. The reading of the balance is W₁ when the satellite goes in an orbit of radius R and is W₂ when it goes in an orbit of radius 2R.

Take the effect of bulging of earth and its rotation in account. Consider the following statement:

(A)There are points outside the earth where the value of g is equal to its value at the equator.

(B)There are points outside the earth where the value of g is equal to its value at the poles.
