The most common force of attraction is gravity.


The force that attracts us to the Earth is called gravity. You live with gravity so I do not need to give you examples of that force. Other possible forces of attraction are electromotive force and magnetic force.

Examples of electromotive force: rub a balloon on a woolen sweater and the balloon will cling to a wall. After running a comb through dry hair, bits of paper can be attracted to the comb. Examples of electromagnetic force: iron fillings will be attracted to a magnet, an electric motor runs because of magnetic attraction.

I hope this helps,

The force that attracts (the mass) of all objects together is gravity.


Gravity as described by Newton is the attraction of one mass to adjacent other masses. Newton's law of universal gravitation is defined here:

There are also other forces that attract objects together, such as electrostatic and magnet forces, but the force of gravity affects all masses.
