If heavier bodies are attracted more strongly by the earth why don't they fal faster than the lighter bodies?

If the force of gravity acts on all bodies in proportion to their masses, why does heavy body not all faster than a light body?

Why a body weighs less at the equator than at the poles?

A lighter body collides with much more massive body at rest. Prove that the direction of lighter body is reversed and massive body remains at rest.

The acceleration of a body due to the attraction of the Earth (radius R) at a distance 2R from the surface of the Earth is .........

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 flattening of the earth at the poles is also taken into account?

Weightlessness in space: Space travellers as well as objects in the spacecraft appear to be floating. Why does this happen? Though the spacecradft is at a height from the surface of the earth the value of g there is not zero. In the space station the value of g is only 11% less than its value on the surface of the earth. Thus, the height of a spacecraft is not the reason for their weightlessness. Their weightlessness is caused by their being in the state of free fall. Though the spacecraft is not falling on the earth because of its velocity along the orbit, the only force acting on it is the gravitational force of the earth and therefore it is in a free fall state. As the velocity of free fall does not depend on the properties of an object, the velocity of free falls is the same for the spacecraft, the travellers and the objects in the craft. Thus, if a traveller releases an object from her hand, it will remain stationary with respect to her and will appear to be weightless. Why doesn't the spacecraft fall towards the Earth?

If neutrons exert only attractive force, why don't we have a nucleus containing neutrons alone?
