Gravity and air resistance is all that I got.
Yes there is - air pressure - and the force of the Earth when it bounces.
action and reaction force
Forces on a moving object are balanced only when the object is moving at a constant velocity. Remember, acceleration is a force and a constant velocity is equivalent to zero acceleration. Think of a ping pong ball that you drop from a few meters above the ground: After a short acceleration the ball reaches "terminal velocity" when the air resistance balances the gravitational acceleration. After this, the forces on the ball are balanced (although it is moving, the velocity - speed & direction - of the ball is not changing)
1) While the ball is kicked, the main force is the force of the foot against the ball.2) While the ball is in the air, the main force acting on the ball - again, an unbalanced force - is gravity.
Equal.

In 3-5 sentences, summarize the balanced forces that are present when a soccer ball is resting on the ground, and the unbalanced forces that are present when a soccer ball is kicked and moves through the air or rolls on the ground
action and reaction force
Unbalanced forces are important in order to move anything. An object under balanced forces does not move. For example as you sit in your chair reading this, gravity is exerting a force on your body downwards but your chair balances this force by exerting a force upwards on you that is equal and opposite to the force of gravity. These two forces oppose each other and therefore you do not move. In tennis in order to change the direction of a tennis ball you need to exert a net force(an unbalanced force) in the direction you want the tennis ball to move. In tennis there are also unbalanced torques(a force acting at a distance from a pivot point) on the ball that cause the ball to spin. Hope that helps.

Bouncing ball was created in 1925.
Either there are none, or if there are any, then the whole group of forces is balanced.

yes a bouncing ball is an example of SHM
We might say that an unbalanced force causes a ball to start moving. If a ball is resting on a surface, gravity is pulling down and the surface is pushing up against it. Things (forces) are in balance and the ball is still. Drop the surface out from under the ball and that ball begins to fall as gravity has no opposing force to balance it.Any lateral force on the ball that can overcome its rolling resistance will cause the ball to move. The inertia of the ball is such that it "wants" to remain at rest. Some unbalanced force will have to act on the ball to cause it to start moving. A ball on a pool table sits still until struck by a cue or another ball. It takes an "outside" force to "unbalance" the forces acting on a ball that is at rest to cause it to move.
