That is the object's terminal velocity.
Acceleration due to gravity is 9.8m/s/s, which is the same as 9.8m/s2. An acceleration of 9.8m/s/s means that with each passing second, the velocity of the skydiver increases by 9.8m/s. Therefore, after two seconds. a skydiver's velocity would be 19.6m/s. The acceleration will continue at 9.8m/s/s until the skydiver reaches terminal velocity, at which point the weight of the skydiver and the air resistance will be balanced, so the net force acting on the skydiver will be zero, at which point there will be no further acceleration.
No. "Free fall" refers to a state in which there is no significant air resistance.
100-N
Yes, if it reaches terminal velocity, which is a constant velocity. When terminal velocity is reached, the downward gravitational force is equal to the upward force of air resistance, and the object no longer accelerates.

terminal velocity
Terminal Velocity. This is the velocity at which the accelaration from Earth's gravity and the drag from air resistance reaches equillibrium.
Panic?Terror?Exhilaration?No, "FREE-FALL". Although one or more of the first three are likely, as well.By the way; a skydiver is only in freefall for about a second after the jump. After that, the air resistance of his body begins to slow him down until he reaches "terminal velocity".
If air resistance is significant, after falling for a while the air resistance will be as strong as the force of gravity; the two forces will be in equilibrium, and the object won't accelerate any more. This velocity is called "terminal velocity". The amount of this terminal velocity, and the time it takes to approach the terminal velocity, depends on the specific object that is falling.
Yes, until he reaches terminal velocity.
The fastest velocity a falling object can reach is called its terminal velocity. This happens when the force of air resistance is equal to the downwards force of weight (gravity), so the object is in equilibrium, and thus reaches a constant velocity.
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.
