Does it mean a skydiver is slowing down if the acceleration of the skydiver decreases as falling progresses?
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.
What else can I help you with?
A skydiver of mass 100 kg experiences air resistance while falling How fast is the skydiver being accelerated at?
The acceleration of the skydiver can be calculated using Newton's second law: F = ma, where F is the force of gravity - air resistance, m is the mass of the skydiver, and a is the acceleration. The acceleration will depend on the exact value of air resistance acting on the skydiver.
When a skydiver has reach the terminal speed what is the air resistance equal to what is the sky diver acceleration?
When a skydiver reaches terminal speed, the air resistance is equal to the force of gravity acting on the skydiver. At this point, the acceleration of the skydiver is zero, as the forces are balanced. This means that the skydiver is falling at a constant speed due to the opposing forces being equal.
Does a skydivers decreases her acceleration when falling 5 seconds before reaching her terminal velocity?
No, a skydiver's acceleration remains constant as they fall towards their terminal velocity. This is because terminal velocity is the point at which the forces of gravity and air resistance are balanced, resulting in a constant velocity.
What direction is the net force on a falling skydiver before she reaches terminal vilocity?
The net force on a falling skydiver is directed downwards, which is the force of gravity acting on the skydiver. This force causes the skydiver to accelerate as she falls until she reaches terminal velocity.
What effect terminal velocity and air resistance have on a sky diver when he opens his parachute?
When a skydiver opens their parachute, air resistance increases which slows down the skydiver. Terminal velocity is the maximum speed a falling object can reach when the force of gravity is balanced by the force of air resistance. Opening the parachute decreases the skydiver's speed, allowing them to land safely.

Does air resistance increase or decrease the acceleration of a falling leaf from a tree?
Air resistance decreases the acceleration of a falling leaf from a tree. As the leaf falls, air resistance opposes its motion, slowing it down. This results in a lower acceleration compared to if the leaf were falling in a vacuum with no air resistance.

The net force on a falling skydiver is directed downwards, which is the force of gravity acting on the skydiver. This force causes the skydiver to accelerate as she falls until she reaches terminal velocity.

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.

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.
How does a open parachute increase the air resistance of a falling skydiver?
by increasing surface area
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.
Use newtons law of motion to explain how a parachute slows a sky diver falling toward earth?
When a skydiver jumps, they are affected by gravity, causing them to accelerate towards the ground. When the parachute opens, it increases the air resistance acting on the skydiver, exerting an upward force that opposes gravity. According to Newton's second law of motion (F=ma), the net force acting on the skydiver is reduced, leading to a decrease in acceleration and a slower descent towards Earth.
