The free-fall of objects (falling objects in vacuum or outside the atmosphere) is solely dependent on gravitational pull (in this case the gravitational pull of the moon) and is not influenced by factors such as weight, density or surface area since there is no atmosphere to resist such factors. Therefore a brick and a feather would fall at the same rate on the moon.
F = GmM / R^2 force of grav
But
A = F / m acceleration due to grav
So,
F / m = GM / R^2 = A
So the acceleration due to grav is GM / R^2
Notice small m is not an important consideration for acceleration in the formula for acceleration due to gravity... we define small m the mass of the smaller object (feather or brick) and big M the mass of the bigger one (moon).
Another way to say this: acceleration with the same force is inversely proportional to mass A= f/m , but the force due to grav is proportional to mass. GMm/R^2. This leads to the cancellation of small m.

When does the mass of an object affect the time of its free fall?
Without air, it doesn't. All objects accelerate in free fall with the same acceleration.If they're dropped from the same height above the surface of the same planet at the same time, they hit the ground at the same time. If any difference is noticed,it's strictly the effect of air resistance. Try it in a tube from which the air has beenpumped out, and a feather and a bowling ball really do fall together.If there is an atmosphere thick enough to produce aerodynamic drag on the object in free fall, then a frictional force will develop in the opposite direction of the objects movement. Terminal velocity occurs when the reactionary drag force and the force due to gravity are in equilibrium. Since a more massive object with the same aerodynamic properties is driven by a greater force due to gravity, it will need to travel faster than a lighter object to acheive an equilibrium in the reactionary drag force. This means the more massive object achieves a higher terminal velocity and reaches the ground faster.If there is no air resistance, it doesn't. However, the size can alter the aerodynamics, providing more or less air resistance.

What is the angle of the moon?
The rate at which the lit portion of the moon moves per hour changes with latitude. The formula for finding the average rate of rotation per hour is: 15°cos(latitude). At the equator the equation would be 15°cos(0°)= 15° per hour.
What is the rate of change of free fall acceleration when an object is released into a free fall and can it be verified experimentally and how?
Take a position equation found experimentally, s(t), and take a double derivative. The first d/dx is velocity and the second is acceleration.
How many hours does it take for the count rate to fall from 300 counts per minute to 150 counts per minute?
To determine how long it takes for the count rate to fall from 300 counts per minute to 150 counts per minute, you need to know the decay constant or half-life of the substance being measured. Assuming a simple exponential decay, the count rate will halve approximately every half-life. If the half-life is, for example, 1 hour, it would take 1 hour to fall to 150 counts per minute. Without specific decay information, the exact time cannot be calculated.
Which one would touch the ground first in a vacumn a brick or a feather?
In a vacuum, both a brick and a feather would fall at the same rate and touch the ground at the same time because there is no air resistance to slow them down. This is because in a vacuum, all objects fall at the same rate regardless of their masses.
Why did the hammer and the feather fall at the same rate on the moon but o earth?
The hammer and the feather fell at the same rate on the Moon because there is no significant air resistance to slow down the feather, unlike on Earth where air creates drag. On Earth, the feather's lightweight and shape cause it to be affected more by air resistance compared to the hammer. This difference in air resistance leads to the hammer falling faster than the feather on Earth, while on the Moon, both objects fall at the same rate due to the lack of atmosphere.
A feather falls through the air more slowly than a brick because of?
If you dropped them in a vacuum, they would fall at the same rate. However, when you do it in air, the friction from the air will slow the feather considerably, as the surface area to mass is much greater then that of the brick.
What should happen if you dropped a hammer and a feather on the moon?
If you dropped a hammer and a feather on the moon, both would fall at the same rate due to the moon's lack of atmosphere, which eliminates air resistance. This means they would hit the lunar surface simultaneously, demonstrating Galileo's principle of falling bodies. This phenomenon contrasts sharply with what happens on Earth, where the feather would fall much more slowly due to air resistance.
What falls faster when dropped on the moon a hammer or a feather?
On the moon, both a hammer and a feather would fall at the same rate because there is no atmosphere to create air resistance. In a vacuum, all objects fall at the same rate regardless of their mass. This was famously demonstrated by astronaut David Scott during the Apollo 15 mission.
Do objects fall at the same rate on a planet with no atmosphere?
No, because there is no air to slow the down. For deeper analysis, check youtube, hammer and feather experiment on the moon. They hit the ground at the same time on the moon because there is no atmosphere, but if you drop a hammer and a feather on earth the hammer, obviously, hits first.
What has to happen for a feather and a ball to fall at the same rate?
For a feather and a ball to fall at the same rate in a vacuum, they need to experience the same gravitational force acting on them. This means there is no air resistance to slow down the feather, and they can both accelerate similarly due to gravity.
What would fall faster a feather or a piece of paper?
In a vacuum, a feather and a piece of paper would fall at the same rate due to gravity. However, in Earth's atmosphere, the feather would fall more slowly due to air resistance.
Why will the lead weight and the feather land on the ground at the same time on the moon?
In a vacuum, where air resistance does not exist, objects of different masses will fall at the same rate due to gravity. This is because all objects are subject to the same gravitational acceleration. On the moon, with no atmosphere to create air resistance, both the lead weight and the feather will experience the same gravitational pull and fall at the same rate, leading them to land on the ground simultaneously.
How does the mass of an object affect the rate of its fall?
It won't affect the rate of fall, which is 9.8m/s2. If you drop a bowling ball and a crumpled ball of paper from the same height, they will land at the same time. The earth's gravity determines the rate of fall. During the Apollo 15 moon landing, a feather and a hammer were dropped from the same height and they landed at the same time. The moon's gravity determined their rate of fall. Refer to the related link to see the demonstration.
Who dropped the feather and hammer in Apollo 11?
Astronaut David Scott dropped a feather and a hammer on the moon during the Apollo 15 mission. This was done to demonstrate Galileo's theory that objects of different masses fall at the same rate in a vacuum.
Can a quarter and a feather fall at the same speed?
theoritically yes. if they are placed in a vacuum packed room with no air, just empty space, they can fall at the same rate. if they fell in air, the aerodynamics wouldn't equal out, so the quarter would fall faster.
