If lighter object in the earth attract earth with the Same force as earth attract it,why does it fall?
Why gravitational force is so called action reaction pair?
1)
There are two forces based on the likeness and dislike.
Attraction.
Repulsion.
Attraction force is application of force to make the other object nearer to the attracting object.
The displacement depends on the neutralization of the inertia and resulting displacement from the original resting place of the attracted object.
We may call it as if the object is being pulled.
In repulsion force the object tries to make other object away from itself.
Negative charge pushes other object which is charged with the same type of negative charge.
Positive charge pushes other object if that is also charged with the same type of positive charge.
Same thing happens with the magnetic force.
Same poles repulse.
In case of attraction either the charge is to be opposite or the pole is to be opposite.
Magnet goes little more as it attracts the magnetively neutral material specially those of mattles.The charge also attract the charge neutral matter.
Then there comes the gravity and it heavily depends on the mass and visibly attracts the gravitons and gravton attracts the lighter objects.
The earth is the graviton so it attract all matters Towards It and inside it.
The gravity is highest at the surface of the earth and inside/ outside the surface gravity is reduced.
Earth also acts as big magnet and its pole are north and south.
Even the magnetic pole have highest attractive force at the poles.
So answer is Earth attracts all matters TOWARDS it.
2)
The weight of the person is the gravitational forceexerted on him by the Earth. The person exerts an equal but opposite gravitational force on the Earth. The forces and form an action-reaction pair.
