Why is is that if a crumpled and smooth paper are dropped, they won't hit the ground at the same time

-Easy. Air friction. The shape is different, which means different forces from air friction. If you did this experiment in a vacuum, both would fall together.......
If a crumpled piece of paper and a smooth piece of paper are dropped at the same time, why don't they hit the ground at the same time? EXPLAIN!!

Thanks in advance!

Easy. Air friction. The shape is different, which means different forces from air friction. If you did this experiment in a vacuum, both would fall together. A good example of air friction in action is a parachute. The skydiver's mass remains the same, but the open parachute increases the amount of force retarding the fall through air. If you watched or have seen the film footage of the moon landings, they did this experiment with a feather and a rock. They brought the feather along and just picked up a local rock and dropped them both. Feather and rock hit the surface at exactly the same time. Back when I was in 8th grade in a science class, we had a glass tube with a penny and a chicken feather. When inverted, the penny fell and the feather floated down. Then, we used a vacuum pump to pump the air out. Then, when inverted, the penny and feather fell together.

Without taking into account air resistance, the two pieces of paper would fall at the same rate (because mass and acceleration due to gravity are equal). However, since the smooth paper would have a significantly larger surface area than the crumpled piece of paper, it would fall slower because it would have more air resistance. Hope this helps :)

it wont drop at the same time because the crumpled paper has more energy and it will drop faster, mean while the paper that is not crumbled, it will take its time, there is no holes or anything for it to pull it down, and the crumbled one does.

-
All objects fall at the same speed, that is a function of gravity, as long as no other factors are present. The factor affecting your experiment is wind resistance. The perfect experiment is in a sealed room with no atmosphere.

-
The smooth paper falls slower because it has more surface area, which means more room for air to catch the sides of the paper.

The crumpled paper has less surface area, therefore falls faster.

-
The smoothed out piece of paper has more of a resistance to falling than the wad of paper does. So dumber version; Flatter paper slow, and compact ball faster.

-
Aerodynamics. The crumpled piece of paper allows the air to flow around it more efficiently than the flat piece.

-
The smooth paper has greater surface area, so it experiences more air resistance during its descent. If you dropped them both within a vacuum, they'd fall to the ground at the same time.

They don't hit the ground at the same time because of air resistance!!! Hope this helped!!!
