At a given instant of time an 8 kg rock is observed to be falling with an acceleration of 7 meters per s squared what is the magnitude of the force of air resistance acting on the rock at this instant?
StephenSpring
Normal acceleration is about 10 meters per second squared, so there is a force backward capable by itself of producing an acceleration of 3 meters per second square. Now use the formula. Now use the formula F=ma.

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.
Does air resistance increase or decrease the acceleration of a falling leaf from a tree?
Air resistance decreases acceleration of falling objects
How does air resistance affect the acceleration of falling objects?
As a falling object accelerates through air, its speed increases and air resistance increases. While gravity pulls the object down, we find that air resistance is trying to limit the object's speed. Air resistance reduces the acceleration of a falling object. It would accelerate faster if it was falling in a vacuum.
What happens to a falling object when the force of gravity equals to the force of air resistance?
the object will floatit shows increasing acceleration
What is the relationship between air resistance and the acceleration of falling objects?
As an object falls towards the earth, it accelerates due to the force of gravity acting on it's mass. As velocity increases, air resistance increases. This is in the opposite direction to the force of gravity on the object. Therefore the resultant force on the object is decreased, and the rate of acceleration is reduced. Eventually, the force due to the air resistance is equal in magnitude to the weight and the object has no resultant force acting. At this point the object will be travelling at a constant velocity, commonly referred to as Terminal Velocity.

Does air resistance increase or decrease the acceleration of a falling obect?
Well, the more the air resistance, the lower the acceleration.
How does air resistance affect the acceleration of a falling abject?
Air resistance creates friction and slows a falling object.
How would the observed value of acceleration be affected if the falling body used were heavier?
Your question describes it as a "falling body", so I'm assuming that you're asking about a body with no force on it except for the gravitational force. This is an important assumption. If it's true, then the mass (weight) of the falling body has no effect at all on its acceleration. Except for the effect of air resistance, all bodies fall with the same acceleration.
Can a body have decreasing acceleration but increasing speed?
Of course. The magnitude (size) of acceleration is the rate at which speed is changing. As long as the magnitude of acceleration is more than zero, speed is increasing. If the magnitude of acceleration is decreasing, then speed is growing more slowly, but it's still increasing. That's exactly what's happening to an object falling through air. As it falls faster and faster, the force of air resistance increases. The object's acceleration shrinks, and it's speed increases more slowly. When the force of air resistance is equal to the object's weight, the net force on it is zero, its acceleration is zero, and its speed stops increasing. It's then at 'terminal velocity'.

Air resistance causes friction and slows an object.

Air resistance reduces the acceleration of a falling object. It would accelerate faster if it was falling in a vacuum.
What is the acceleration of falling bodies?
Near Earth's surface, the acceleration is about 9.8 meters/second2, assuming air resistance can be neglected.
A falling stone has zero acceleration?
Only if it has enough wind resistance to cancel out gravity.
What acceleration does the object reach when air resistance equals the force of gravity on a falling object?
the acceleration of gravity is 9.8 m/s
What is the acceleration of a falling abject?
All objects irrespective of their masses in a vacuum where there is no air resistance will fall at an acceleration of 9.81 m/s²
