Air resistance increases and terminal velocity decreases when the parachute has opened.
The cumulative effect of gravity and air resistance determines an object's terminal velocity. Initially, gravity accelerates the object, while air resistance acts in the opposite direction. As the object gains speed, air resistance increases until it becomes equal in magnitude to the force of gravity. At this point, the net force on the object is zero, resulting in a constant terminal velocity where the forces are balanced.
Vibration does not have a significant effect on terminal velocity. Terminal velocity is the constant speed that an object reaches when the force of gravity pulling it down is equal to the force of air resistance pushing against it. Vibrations are typically not strong enough to significantly alter this balance.
Not necessarily. Terminal velocity depends on a combination of factors like weight, drag coefficient, and surface area. So while a larger sphere may experience more air resistance due to its increased surface area, it might also be heavier, which can offset this effect.
If someone is skydiving, the terminal velocity would be the greatest velocity reached by the falling person until they open their parachute. So in that case, the effect would be slowing down because of the parachute. The effect may vary from different cases.
The less air resistance the faster he can go. By pointing his face or feet down and holding his arms close to his body he minimizes air resistance and falls faster. By positioning his body parallel to the ground and spreading out his limbs he maximizes air resistance and will fall slower. The type of clothing worn also has an effect. A loose fitting fabric jumpsuit will tend to reduce terminal velocity and a tight fitting nylon jumpsuit will increase it. Some jumpers wear lead weight to adjust their fallrate. This is usually so slim light jumpers can match their fallrate with heavier jumpers.

interesting: in effect you are, because you have reached the terminal velocity for your surface area, which happens to be very large! if wrong, someone please correct me.

-- The force of gravity is unchanged before and after.-- The force of air resistance on the skydiver is greater before, and less after,because she is falling slower after the parachute opens.-- The effect on her of air resistance is greater after the parachute is open. Theincreased air resistance itself acts on the parachute, and its effect is transferredto the skydiver through her harness.

The size of the parachute affects air resistance because a larger parachute will have more surface area interacting with the air, creating more drag. This drag helps to slow down the descent of the object attached to the parachute. Conversely, a smaller parachute will generate less air resistance and may result in a faster descent.
Terminal velocity is the speed at which air friction produces enough drag to balance the effect of gravity and cease acceleeration (keeping the subject at a constant speed downward). For an unaided person, it is almost certain death since t.v. for us is about 200km/h. However with a parachute we are slowed to speeds at which we will easily survive.
The ball returns to the ground with increasing velocity due to acceleration due to gravity. At a point (terminal velocity) the ball maintains a constant velocity (due to air resistance) This occurs when the weight of the ball is equal to the viscous drag of the air (air resistance) and upthrust (weight of air displaced).

This is called Terminal Velocity. Gravity pulling downwards matches the air resistance pushing upwards to cancel the acceleration out. Many people misunderstand this and believe that this means that the object falling is no longer moving, but it is speaking in terms of acceleration, not speed. So the acceleration from before terminal velocity was reached will still be in affect, but the object will be neither gaining or losing speed.
