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.
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.

A skydiver typically achieves terminal velocity within 10-15 seconds after jumping out of the plane. Terminal velocity is reached when the force of air resistance pushing up on the falling object equals the force of gravity pulling it down, resulting in a constant falling speed.
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.
Yes. Not just a skydiver; anything that falls long enough will eventually reach "terminal velocity", which means that it will continue falling at a constant speed, because the force of gravity and the force of air resistance are in balance.

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.
The mass of a skydiver remains constant while they are free falling. Mass is a measure of the amount of matter in an object and does not change regardless of the forces acting on it, such as gravity or air resistance. However, the skydiver's weight, which is the force of gravity acting on their mass, changes due to the effects of air resistance as they accelerate and reach terminal velocity.

To start with there is gravitational attraction. As soon as the skydiver starts falling, (s)he will experience the drag force due to air resistance. The gravitational force is essentially constant but the drag increases as the diver's velocity increases until it equals gravity. The diver is the falling at terminal velocity and will continue to do so until the parachute is operated.
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.
