Why a skydiver falls towards earth even when he is under the influence of balance forces?

"Balanced forces" doesn't mean that an object doesn't move. "Balanced forces" means that the vector sum of forces on an object is zero. Now, according to Newton's First Law, if no force is acting on an object, if that object is at rest it will continue being at rest; if it is moving, it will continue moving with the same velocity. In other words, there will be no CHANGE in velocity; that doesn't mean that the velocity must necessarily be zero.

What are the forces acting on a skydiver?
Drag, I think? drag is good
How does forces affect the sport of sky diving?
Gravity pulls the skydiver towards the centre of the earth (downwards force). The air causes wind resistance, slowing the sky diver down (upwards force). The wind can also cause a slight sideways force upon the skydiver.
How much air resistance acts on a 500 N skydiver that falls at her terminal velocity?
500 N is pressumably the weight, due to gravity. "Terminal velocity" means that the forces are in balance; the total force acting on the skydiver are zero. This is only possible if there is a 500 N force due to friction, to counteract the weight.
Are the forces balanced or unbalanced when a skydiver is accelerating downward?
An acceleration requires an unbalanced force.
When a skydiver jumps out of an airplane there are two forces acting on her gravity and air resistance After falling for a few seconds the forces due to gravity and air resistance balance each other?
Your question is slightly confusing as you seem to have answered it yourself. A little extra though, the speed at which the skydiver is now travelling is called terminal velocity and it is the fastest an object can travel with only gravity + air resistance acting on it as forces. Due to differing air resistances everything has its own unique terminal velocity and it is possible to alter it, this is the principle behind a parachute.
What happens to a moving object with zero nets force acting on it?
Certainly. Say you have an object that has been falling through the air for a long time, say a skydiver. After falling for a long time, the skydiver will fall at a constant velocity. This is called terminal velocity, and this is when the air resistance pushing up around the skydiver is equal to the force of gravity pulling the skydiver down. The skydiver is not accelerating. By using F= ma, with zero acceleration, there is zero net force. The skydiver is moving as if there are no forces acting on the skydiver.
What forces work on a skydiver?
(standard air pressure and gravity)>(Constant) Force down (newtons) = mass * acceleration due to gravity>Say 70 kg skydiver @ 9.82 m/s/s = 70 * 9.82 = 687.4 newtons>Force up (newtons) = velocity 2 * drag coefficient (say 0.16 typical)>Terminal velocity (when forces balance) 687.4 = v 2 * 0.16Terminal velocity = square root (687.4 / 0.16)= 65.546 metres per second ( 147 mph) terminal velocity
What forces act on a skydiver as they are diving?
when a skydiver jumps out of a plane, the dominant force is gravity, pulling him/her towards the ground, although some air resistance is also acting on him/her, allowing him/her to fall at a steady speed (not dropping like a stone), so the forces acting on the skydiver are almost balanced. of course, all that changes when the parachute opens. then the air resistance greatly increases, drastically slowing the descent down to earth.
What is a state in which all forces acting on an object are in balance?
Equilibrium is a state in which all forces acting on an object are in balance.
Why don't two forces balance each other?
Two forces do balance each other out, as long as the two forces are equal in magnitude and opposite in direction.
When forces do not balance the object will be?
Accelerating
Why don't some forces balance each other?
That's because forces will ONLY balance under very specific circumstances.
