Found that metallic objects, usually more dense than other materials, fall
faster than wood objects because gravity is like a magnetic field which
attracts more intensively metallic objects than wood objects. I've made the
experience at home. But this goes against what I learned in school. Teachers
told me that the velocity of falling objects isn't related with the object's
mass. Could I say that there is electromagnetic field in my home's floor or
is this normal condition?

Found newton's apple formula... they worked with chronometer.

Your observations have nothing to do with the mass or density of the
objects. It is simply a matter of air resistance. Two objects with the
same volume, shape and surface area will fall at different rates of
acceleration if they are not of equal mass. Something like a Styrofoam
cube 1 cm square and a lead cube of the same size will experience the
same air drag but will definitely have a different gravitational force
causing their different free fall acceleration rates. Gordon
