Well it really depends on several factors that have to be just right in order for two objects to fall at the same speed or rate.
The three main factors needed to calculate the speed at which two objects fall are Time(t) Velocity(v) and Rate of Acceleration.
The formula used to calculate is:
Acceleration= v-u/t (the v-u is change in velocity)
A marble and a bowling ball fall at the same acceleration speed. Anything with the exact same shape falls at the same velocity. 10 meters/s/s
That depends. 10 lbs. of bricks will fall at the same speed as 10 lbs. of feathers. Meanwhile, a cinderblock will fall far faster than a single feather. If two things are the same weight, they will usually fall at the same speed. If two things are different weights, they will fall at different speeds. ^ This only takes effect when wind resistance is NOT added.
In a vacuum, air resistance is eliminated, and all objects fall due to gravity alone. The acceleration due to gravity is the same for all objects regardless of their mass, so they fall at the same speed in a vacuum.
Galileo Galilei, an Italian scientist, is credited with the discovery that heavy and light bodies of the same substance fall at the same speed in a vacuum. He conducted experiments to demonstrate this principle of free fall.
Indeed, in a vacuum or in air with negligible air resistance, quarters and feathers would fall at the same speed due to the acceleration due to gravity being the only force acting on the objects. This is in accordance with the principle of universal free fall.
all things fall at the same speed
Isaac Newton

both will fall at the same time
iT DEPENDS IF THE BALL IS LIGHT THE LIGTER MOSTLIKLEY TO HAVE THE SAME SPEED.
That depends. 10 lbs. of bricks will fall at the same speed as 10 lbs. of feathers. Meanwhile, a cinderblock will fall far faster than a single feather. If two things are the same weight, they will usually fall at the same speed.

In a vacuum sealed room, yes, they can. If not, then without properly balanced air resistence, no. The only reason objects fall at different speeds is because of air resistence/terminal velocity, things of that nature. When dealing with air, and etc... if you want them to fall at the same speed, they have to have the same air resistence (a combination of space taken up, and mass.) So yes, they could fall at the same speed, but the yarn would probably have to be coiled extremely tightly.
Air resistance of an object can slow its fall. If every object had the same resistance, everything would fall at the same speed.
In a vacuum.
In a vacuum, air resistance is eliminated, and all objects fall due to gravity alone. The acceleration due to gravity is the same for all objects regardless of their mass, so they fall at the same speed in a vacuum.
Galileo showed that all bodies fall at the same speed under gravity. He performed his experiments assuming air resistance is ignored.galileoGalileo
