The force (F) of gravity acts on the mass (m) to result in acceleration of the object due to gravity (g). F=mg.
Mass has virtually no effect on acceleration during free fall. Galileo demonstrated this when he dropped lead balls of various masses.
Here is Newton's equation for force due to gravity:
F = G * M * mo / (rE + h)2
where
G = gravitational constant = 6.67300 × 10-11 m3 kg-1 s-2
M = mass of planet (If this free fall is near Earth, use 5.9736 × 1024 kg
mo = mass of object 2 (object in free fall)
rE = the radius of the planet, moon, star, etc. where the free fall is occurring (If Earth, at 0º latitude, use 6378137 m; at 90º latitude, use 6356752 m, interpolate for latitudes in between)
h = elevation of the object free falling, from "sea level"
Gravitation is not entirely understood, but we know it acts both ways. As the falling body is pulled toward the Earth, the Earth is also also being pulled toward the falling body. This latter effect is tiny for all but very large incoming objects (moons, planets and such), but it's still there. Mathematically, you would add these two forces to get the total force, but this second force is ignored unless the body you're interested in has a gravitational field of its own worth accounting for.
Force due to gravity that we normally care about is F = mog. But let's say there are two forces (F1 and F2) due to two accelerations (g1 and g2). The two forces to be added together are
F1 = mog1 (the force we usually care about calculating)
F2 = Mg2
(This is the tiny force that pulls the planet of mass M toward the falling body)
mog1 = G * M * mo / (rE + h)2
g1 = G * M / (rE + h)2
Mg2 = G * M * mo / (rE + h)2
g2 = G * mo / (rE + h)2
Note that mo dropped out of the g1 solution, meaning the acceleration g1 just calculated is not affected by the falling objects mass. Similarly, M falls out of the solution for g2: the mass of the planet does not affect its acceleration toward the falling body.
When you add F1 and F2 to equal the total actual force in this system you get
mog1 + Mg2 = G * M * mo / (rE + h)2
and
g = g1 + g2
Solving for g2:
g2 = G * mo / (R^2 * (1 + M / mo))
So, g2 and thus F2 are both partly a function of mo, the falling object's mass, but only very slightly since mo is tiny compared to M. Considering you are dividing the gravitational constant (a small number to begin with on the order of 10-11) by the Earth's radius squared and again by the ratio of the Earth's mass to the objects mass, the tininess of this force can boggle the imagination and can be safely ignored for any experiment you would be trying yourself!
Terminal Velocity:
In an atmosphere the density of the object (mass/unit volume), shape and aspect may change the terminal velocity by increasing or decreasing the aerodynamic drag. In a long enough fall the heavier object will pull ahead of the lighter object due to its higher terminal velocity. But the acceleration will not be affected, practically speaking.
No, a simple pendulum cannot oscillate during free fall motion because in free fall, the object is accelerating due to gravity and there is no restoring force acting on the object to cause oscillations.
Free fall is a type of motion where an object falls under the influence of gravity with no other forces acting upon it. During free fall, the object accelerates downwards at a constant rate of 9.8 m/s^2 on Earth.
Friction can slow down the rate at which an object falls by exerting a force in the opposite direction of the object's motion. This opposing force can reduce the object's acceleration and result in a slower fall.
Projectile motion involves an object moving both horizontally and vertically, while free fall is when an object falls only vertically due to gravity. In projectile motion, the object has an initial horizontal velocity, while in free fall, the object is only affected by gravity.
The factors that affect the speed of an object in free fall with air resistance are the object's mass, the surface area of the object, the density of the air, and the gravitational force acting on the object.

It doesn't. In air, the object may 'fall' at a different rate, depending on any aerodynamic qualities it may have, but otherwise an object will fall at the same rate without respect to it's lateral motion. Of course, unless the object is in a vacuum, its aerodynamic qualities, however limited, will impact the rate at which it falls.

Projectile motion involves an object moving both horizontally and vertically, while free fall is when an object falls only vertically due to gravity. In projectile motion, the object has an initial horizontal velocity, while in free fall, the object is only affected by gravity.
The higher the concentration of a fluid, the longer the time it takes for an object to fall and therefore the smaller the terminal velocity.
Yes, unless speaking about parachutists who refer to free fall as falling through the air without opening their parachutes.
The factors that affect the speed of an object in free fall with air resistance are the object's mass, the surface area of the object, the density of the air, and the gravitational force acting on the object.
Yes, free fall refers to the motion of an object falling solely under the influence of gravity, without any other forces acting upon it. The vertical component of motion in a free fall is the object's downward movement due to gravity.
Without propellers, jets, or a parachute, an object can't to anything to affect its acceleration when it's falling. "Free fall" means moving under the influence of gravity only, with not even any air resistance. In that situation, on or near the surface of the Earth, acceleration is constant, regardless of the size, shape, mass, weight, or gender of the falling object. That number is 9.8 meters (32.2 feet) per second2 ... known as the acceleration of gravity on Earth.
Gravity affects the motion of an object by pulling it towards the center of the Earth. This force creates acceleration, causing objects to fall towards the ground at a rate of 9.8 m/s^2. The greater the mass of an object, the greater the gravitational force acting upon it.
