In the absence of air, size has no effect whatsoever. Where the fall is through
air (or any other fluid), then it's slowed by both shape and size.
False. A leaf floating down a tree is not an example of free falling because it is not accelerating due to gravity alone. The air resistance and other factors affect its descent, making it a non-example of free falling.
Yes, a feather is considered a free falling object in a vacuum or an environment with minimal air resistance. However, in normal atmospheric conditions, air resistance can significantly affect the feather's rate of descent.
No, changing the mass of a free-falling body does not affect the value of the acceleration due to gravity. The acceleration due to gravity is a constant value that is independent of the mass of the object. All objects fall at the same rate in a vacuum 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.
False. Free falling objects accelerate at a rate of 9.8 m/s^2 due to the force of gravity acting on them. The force of friction and air resistance do not significantly affect the acceleration of free falling objects in a vacuum.
Only if it's falling through air. If it's just the falling object and gravity, then no.
Yes, unless speaking about parachutists who refer to free fall as falling through the air without opening their parachutes.
False. A leaf floating down a tree is not an example of free falling because it is not accelerating due to gravity alone. The air resistance and other factors affect its descent, making it a non-example of free falling.

The terminal velocity of a falling object depends upon its aerodynamics (which is to say, its shape) rather than its size and mass.
False. Free falling objects accelerate at a rate of 9.8 m/s^2 due to the force of gravity acting on them. The force of friction and air resistance do not significantly affect the acceleration of free falling objects in a vacuum.
Two factors that greatly affect air resistance on falling objects are the size and shape of the object. Smaller objects and objects with a more streamlined shape experience less air resistance compared to larger or less aerodynamic objects.
