If you drop a pound of rocks and a pound of feathers off a building at the same time which will land first?

Answer 1

BOTH, they weigh the same.

Answer 2

Wow, those answers were all over the place.

If you didn't have to worry about air resistance, they would land at the same time. That's NOT because the rocks weight more (they don't) and NOT because the rocks are more dense (same weight, doesn't matter) - it's because the gravitational acceleration is the SAME on ANYTHING you drop - a brick would fall at the same speed as a feather, neglecting air resistance.

However, you have air resistance on the Earth, so the rocks would hit first because they ARE denser, thus taking up less volume, and have less air pushing back against them as a result.

Answer 3

the rocks will land first. a pound of rocks is small and and pound of feathers is large. The feathers will catch a lot of air and slow the drop. In a perfect vaccume they will fall at the same time but on earth there is something called air and wind resistance

Answer 4

The rocks would land first, because since feathers are less dence than rocks, a pound of feathers would take up more space than a pound of rocks, and there would be more air resistance affecting the feathers, which would slow them down.

Answer 5

How cute... I know people would FIRST think the feathers would be last because they weigh less than rocks.. BUT you have a POUND of each so they'll both land at the same time. ( depending if you drop each one at the same time. :)

Answer 6

on earth: the rocks

on the moon: both will land at the same time


the key is wind resistance. No air on the moon!


try dropping a book with a feather on the top of it. the feather will drop with the book, until it catches an air current.

Answer 7

the exact answer depends of the packaging that the objects are in. Since regular people can't eliminate the effects of the atmosphere and wind we have to take that into account.

In real life the rocks would reach the ground fractions of second before the feathers.

The feather packaging would be larger and would have more Resistance falling through the atmosphere

Answer 8

Both will land at the same time. ! lb is one lb. Now if you said a bucket of rocks and a bucket of feathers, Of course the answer would be the rocks.

GOTCHA!

Answer 9

they land at the same time ...the weight...ONE POUND is the same

while the pack of feathers will be larger, both bodies will fall at the same rate

Answer 10

Both because they both weigh a pound. Neglecting air resistance of course. Even if they weighed differently, they would still hit at the same time if you neglect air resistance.

Answer 11

The rocks because they have more mass than the feathers.
