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.
The forces involved in the freefall part of a skydive are Gravity and air resistance (drag). As the parachute is deployed, drag opens the canopy and the skydiver's weight provides tension on the lines. When the canopy has opened, the skydiver's weight is supported lift provided by the canopy. The canopy also generates thrust and drag, like an aeroplane's wing.
There are many:
The obvious force is gravity. This is the effect of space-time being warped by the mass of the earth, but it is more simply what pulls us towards the ground. Then there is the force of air resistance or drag which increases with downward speed to a point where it balances the gravitational pull. There is also another force, centrifugal force which tends to act at right angles away from a spinning body. If you intentionally spin in freefall, you can feel a tingling in your fingers and toes as the blood rushes outwards. This is the effect of centrifugal force. By changing your body position which involves the bio-mechanical forces in you muscles, hey a force we haven't yet considered, `we can change the balance of the other forces to the point where we have control over our skydive, approaching another jumper and linking up. There are chemical forces in our brain which are involved in the thinking process.
It would seem that there are forces involved that we might not consider at face value.
Gravity pulling the skydiver to the ground as well as wind resistance pushing up on the skydiver.
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.
Drag, I think? drag is good
An acceleration requires an unbalanced force.
cartomancy
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.
Forces don't act on other forces - forces act on objects.

well the forces, and ally kind of physic rules...
