Does it mean a skydiver is slowing down if the acceleration of the skydiver decreases as falling progresses?
Girlneedinghelp
No.
Acceleration is a measure of the rate of change of velocity (speed & direction). If acceleration is decreasing (but still above zero) then this means that the rate at which the speed is increasing in this direction is decreasing.
As long as the downward acceleration is greater than zero then the skydiver's speed is still increasing.
Once terminal velocity is reached then downward acceleration will equal zero (speed is constant).
If the downward acceleration falls below zero (as will happen once his parachute is deployed for instance) then this means he is slowing down.

A skydiver of mass 100 kg experiences air resistance while falling How fast is the skydiver being accelerated at?
Less than 9.8 meters (32.2 feet) per second2.That would be his acceleration ... and also the acceleration of the feather falling next to him ... if there wereno air at all.
What happens to a moving object with zero nets force acting on it?
Certainly. Say you have an object that has been falling through the air for a long time, say a skydiver. After falling for a long time, the skydiver will fall at a constant velocity. This is called terminal velocity, and this is when the air resistance pushing up around the skydiver is equal to the force of gravity pulling the skydiver down. The skydiver is not accelerating. By using F= ma, with zero acceleration, there is zero net force. The skydiver is moving as if there are no forces acting on the skydiver.
What happens to the acceleration of an object as it falls through air?
-- If you really mean "falls through the air", then its acceleration steadily decreases. -- If you're actually thinking about an object that's "falling", with no air in the way and no other influence on it except gravity, then its acceleration is constant as it falls.
How does an open parachute increase the air resistance of a falling skydiver?
by increasing surface area
Acceleration of a falling coin on tower?
The acceleration of falling objects in Earth is about 9.8 m/s2.

Does air resistance increase or decrease the acceleration of a falling leaf from a tree?
Air resistance decreases acceleration of falling objects
What is the skydiver acceleration?
Upon leaving the aircraft, a skydiver rapidly reaches something called terminal velocity. This is where the resistance of the air matches the mass of the skydiver. At this speed, the skydiver maintains a relatively constant speed. Typically this is around 120mph in a flat body position and takes approximately 10 seconds to reach. For more questions about skydiving, see the attached link.

How does air resistance affect the acceleration of a falling object-How does air resistance affect the acceleration of a falling object?
It reduces the acceleration of the falling object due to friction.

What is the acceleration of a falling object?
The acceleration of a falling object is called gravity. A free-falling object has an acceleration of 9.8 m/s/s when going downward on Earth.

How fast is the acceleration of a falling body?
if body is free falling state its acceleration would be 9.8meter/second2
How fast is a skydiver after falling 3 seconds if they accelerate at 10 meters per second?
The acceleration is expressed in meters per second square, which really means (meters / second) / second. Every second, the skydiver will be 10 meters per second faster than the previous second. Therefore, after 3 seconds, he will have a speed of 30 meters per second.
