Detailed explanation-1: -As gravity is the only force in both cases, both balls will hit the ground at the same time.
Detailed explanation-2: -Heavier objects hit the ground first as they have very less air resistance.
Detailed explanation-3: -Which ball hits the ground first? Both balls hit the ground at the same time. This is because the vertical motion is completely independent of the horizontal motion.
Detailed explanation-4: -Given two objects of the same size but of different materials, the heavier (denser) object will fall faster because the drag and buoyancy forces will be the same for both, but the gravitational force will be greater for the heavier object.
Detailed explanation-5: -When you drop a ball (or anything) it falls down. Gravity causes everything to fall at the same speed. This is why balls that weigh different amounts hit the ground at the same time. Gravity is the force acting in a downwards direction, but air resistance acts in an upwards direction.
