In a vacuum, both objects will land at the same time.

Drop a bowling ball and a marble. They will both hit the ground at the same time. The acceleration due to gravity is the same for every falling object regardless of its weight. Now, depending upon air resistance, one item may hit the ground before the other. But, think of the experiment done on the Apollo (15 I think) moon mission. One of the astronauts took a falcon feather and a hammer and dropped them both at the same time. Since there is no air on the moon, they both hit the lunar ground at the same time.

I suppose to give an annoying, technical answer to your question, the object that would hit the ground first (assuming both objects were released from the same height above the ground; also that one was not thrown at the ground) would be the one with the least air resistance--which is why it is better to be the one with the parachute than the one without, you may not get there first, but you'll get there okay.

Sorry, forevermaths, but the story of Galileo dropping things from the tower of Pisa is mostly like just that: a story. He worked out his information by rolling balls down ramps with marked distance scales.

On the original question, I can't understand why so many people can't get this. In a vacuum, like on the moon, the weight or air resistance of the objects has no effect; they will fall at the same speed, and hit the ground at the same time. One of the Apollo 15 astronauts did exactly that, dropping a feather and a hammer at the same time, and they hit the ground together.

On Earth, where we have an atmosphere, it would depend more on the air resistance of the object than its weight, or even density. A 1 pound steel ball would fall much faster than a 4x8 sheet of plywood (less dense), or a thin sheet of platinum (much more dense), even though both the sheets weigh substantially more than the ball.

In a vacuum, they would both land at the same time. Otherwise,
if both objects are of the same shape and density, the heavier object would have a higher ratio of mass to surface area and should therefore be less effected by air resistance and land slightly before the lighter object.

They'll both land at the same time. In the equation in physics (can't remember which exactly) the mass of the object cancels out, so mass is not important. This is barring air resistance, of course, which is why a piece of paper will fall more gracefully than a ball of paper.

I saw the example if physics class where they used a vacuum (container with no air) and droped a feather and a ball inside it. They both landed at the same time.

I will tell u a story. Once upon a time there was a scientist named Galileo. He went up the "leaning tower of pisa". He had the same query that u have have here. He had two balls...ofcourse everyone has two balls but these are two balls he carried in his hand. One heavier than other. He droped both at the same time. they kept fallig .....falling.....falling..... . Both the balls landed at the same time. Moral of the story : Gravity acts equally on objects with different masses.
The above story is not a work of fiction...its a true story.
However wind resistance acts differently on different shapes, but if considered only the weight...speed of falling would be same.

t depends to so many different things the size of each object the shape of each object the weight of each object and also the altitude that you are dropping them but no matter what in vacuum the they will land at the same time

It depends of the shape of the objects. A round object will fall faster than a cube due to resistance and friction. If both objects are the same shape( cube, orb etc) and different weights they should hit the ground at the exact same time.

They will both fall at the same time. according to Newton, the mass of the falling object has no effect on the speed of it's fall (it has to do with his formula for gravity and the classical formula for accelaration and is a bit difficult to explain here). All objects falling to Earth fall with the same velocity (just under 10 meters per second), so if the start at they same height at the same time they wiil fall together, unless one of them is signifcantly more aerodynamic then the other. In the later case the resulting reduction in air resistance will allow that object to reach the grownd first.

Idiots!!! If I drop a piece of paper and a marble from the top of the Empire State building they will not land at the same time. It really depends on the shape of the items in question. Are they the same shape?
