Show law of gratify if a person were to take two round balls each five inches in diameter with one heavier than the other and dropped from the same elevation under favorable weather conditions the two balls will strike the earth at the same time since conditions condition were fixed so the resistance was the same on each tho the earths pull on every small particle of like mass is equal the force on the heavier ball is greater than on that of the lighter ball but since the mass of the heavier ball is greater than that of the lighter ball in the same proportions the accelerations on the two balls will be equal consequently their velocities are equal |
