    Galileo’s law of falling bodies states that the rate of fall caused by gravity is the same for all objects, regardless of weight. This means that all objects have a free-falling acceleration of 9.8m/s2. However, a significant contradiction of this theory

    is carbon dioxide an example of ion-dipole force? I say no, because it is nonpolar since ion-dipole force is an attraction between an ion and polar molecule.
