A golf ball falls to the earth faster than a beach ball because of the force of air resistance. A beach ball is much larger than a golf ball so more force acts on it by air particles resisting its downward motion, making it fall slower. Also, golf balls with their dimples are more aerodynamic: their shape reduces the amount of resistance it faces moving through air. It is also important to say that in a vacuum the masses of objects do not affect their falling times so a golf ball and beach ball would fall at the same rate in a vacuum.
