This all is possible, though. This law of physics doesn't take air resistance into account. So if one ball just happens to be more susceptible to the effects of air resistance, then it would fall slower, and this usually depends on surface area and object composition. So if this is the case, then the light ball is likely made of a different material. Or it can simply be dismissed as human (yukkuri?) error. I'm overthinking it.
It is a well known law that We could possibly subvert the second law of thermodynamics...Awesome!I crudely taught it math, physics, science, electronic engineering, and metal engineering one time through.Really, just crudely.Two objects of different weight will fall at the same speed.......It is probably better to let that do as it pleases...#323 Conquering Galileo!
