stick to something immovable with glue.
The balloon falls slower than a marble because its buoyancy is greater and because its drag coefficient is greater.
higher inertial mass
1. when you drop a feather and a hammer the feather falls slower than the hammer
Air resistance.
Wind resistance. In a vacuum, feathers and bricks fall at same speed.
th fether would usually drop slower becuase of weight if not (then it must be a huge fether.) So please do not look up this question again even though i'm no science person find a REAL EXPERT for your question thx
The most important contributor to the erosion of marble gravemarkers is acid rain. Normal rain erodes marble also, but at a much slower rate than acid rain.

The paper has more surface area and therefore more air resistance than the marble does. If you wad up the sheet of paper in a tight ball, you'll see very little difference in the falling speed.
this is because of air resistance which increases with surface area of feather. however if there is no air resistance (only vacuum) both feather and ball will fall together.
You should change your hypothesis if the results from your experiments do not match what your hypothesis predicted. For instance, you make a hypothesis that a feather will fall at the same speed of a bowling ball. You drop both at the same time a number of times. You see that every time the bowling ball falls at a faster speed than the feather. You would have to change your hypothesis since it doesn't match your results. Your new hypothesis would be that a feather falls at a slower rate than a bowling ball.
It doesn't. But what makes a book fall faster (seemingly) than a feather or piece of paper (lets say) is air pressure, and the way it is shaped.
