Question

a bowling ball a baseball a bird feather

Answer 1

Popo B, you are falling for the fallacy!!!!!!

The rate at which the objects fall is indpendent of mass!!!! If we ignored air resistance, they would all hit at EXACTLY the same time!!!!!

However, if we do account for air resistance, it would go like this.

The feather would hit first since it has the most surface area exposed (NOT because it's the lightest!!!!!!).

The bowling ball would hit just a fraction BEFORE the baseball since it has just a fraction more surface area exposed to the baseball (since it's radius is larger).

The baseball would hit last.

It may be tough to determine which would hit first between the baseball and bowling ball. But believe me, it's NOT because one is more massive!!!!!!!

Answer 2

There are two forces you need to consider here: 1) gravity and 2) air resistance (drag). Here's the answer considering these two things:

1) Gravity accelerates all objects at the same pace -- approximately 9.8 meters per second squared. Interesting factoid: when Galileo figured this (and other stuff) out, he was called a heretic. So that takes care of gravity. If no other forces were acting on the objects, they would hit at the same time.

2) Drag! This it really complicated... So I'll try to make it succinct without getting the facts wrong. For any (free falling) object, the force of air resistance can usually be represented by: F = -Cv where F is the Force of air resistance toward Earth, C is a constant (different constant for each object!), and v is velocity. C is determined by many factors, the most important in this case being surface area.

Lets also state, for the record, that if each object starts with a velocity of zero and free falls, the one which hits the ground first will also be the one with the highest velocity and greatest acceleration at the time it hits. (This is totally intuitive, though the science behind it is actually complicated.)

So we have two forces fighting here, but instead of good and evil, it's gravity and air resistance! because F=ma, the gravitational force exerted on the bowling ball is the greatest, followed by the baseball. This means that it will take a much greater C to slow down the bowling ball than the baseball. Basically, which object will fall faster depends on its mass and surface area.

The wikipedia article listed below has the math-y explanation of exactly how this works, but for an object starting at rest and falling from a large height, a terminal velocity of mg/c will be reached. For your objects, we will define/estimate:
Surface Area (SC) of feather: A
SC of baseball: A
S of bowling ball: 5A
Mass of feather: M
Mass of baseball:500M
Mass of bowling ball: 25,000M

So:
Terminal velocity of feather: Mg/A
Terminal velocity of baseball: 500Mg/A
Terminal velocity of bowling ball: 5,000Mg/A
g is acceleration due to gravity and is the same for all objects.

So, the bowling ball will hit first, then the baseball, then the feather. Oddly enough, in this scenario the heaviest actually will hit first! But this is NOT due to gravity; it is due to air resistance!

Answer 3

One of the NASA astronauts proved this on the moon. A golf ball and a feather were both dropped from the same height at the same time, and both reached the surface together.

On Earth it's only wind resistance that causes the speed of a falling object to change. According to acceleration, all three objects should fall at the same time.

Answer 4

The bowling ball will fall first, followed by the baseball, then the feather.

The bowling ball will be first because it has the most mass, therefore having more weight(W=mg). A higher weight will result in a higher terminal velocity. The same goes through for the baseball and feather.

Answer 5

I believe the speed of "gravity" or rate of fall is the same for ALL falling objects. Gravity is constant. It does not change with an objects weight.

Answer 6

You need to determine the angle at which your working with and atmospheric pressure
