Air resistance acting on a skier.

To solve the problem, we need to identify the type of force illustrated in each picture. Let's analyze each image step by step:

Top Row:

1. Image 1 (Skier):
- The skier is using poles to push off the ground.
- This is an example of an Applied Force because the skier is applying a force manually using the poles.

2. Image 2 (Skydiver):
- The skydiver is falling through the air with arrows pointing downward.
- This is an example of Gravity Force because the force acting on the skydiver is due to gravity pulling them toward the Earth.

3. Image 3 (Person Pushing a Shopping Cart):
- The person is pushing a shopping cart, and there are arrows indicating resistance forces.
- This is an example of Friction Force because the resistance is likely due to friction between the wheels of the cart and the ground.

Middle Row:

4. Image 4 (Parachute Jumper):
- The parachute jumper has arrows pointing upward, which counteract the downward force of gravity.
- This is an example of Air Resistance because the parachute creates drag that opposes the motion of the jumper.

5. Image 5 (Spring):
- The spring is compressed or stretched, and there are arrows indicating restoring forces.
- This is an example of Spring Force because the force is exerted by the spring as it tries to return to its equilibrium position.

6. Image 6 (Magnet and Metal Object):
- A magnet is attracting a metal object.
- This is an example of Magnetic Force because the attraction is due to the magnetic field of the magnet.

Bottom Row:

7. Image 7 (Tug of War):
- Two teams are pulling on a rope, and there are arrows indicating tension.
- This is an example of Tension Force because the force is transmitted along the rope due to the pull from both sides.

8. Image 8 (Ball Floating in Water):
- A ball is floating in water, and there are arrows indicating upward and downward forces.
- This is an example of Buoyant Force because the ball is experiencing an upward force due to the water displacing its volume.

Final Answer:

- Image 1: Applied Force
- Image 2: Gravity Force
- Image 3: Friction Force
- Image 4: Air Resistance
- Image 5: Spring Force
- Image 6: Magnetic Force
- Image 7: Tension Force
- Image 8: Buoyant Force

\boxed{
\begin{array}{ccc}
\text{Applied Force} & \text{Gravity Force} & \text{Friction Force} \\
\text{Air Resistance} & \text{Spring Force} & \text{Magnetic Force} \\
\text{Tension Force} & \text{Buoyant Force} &
\end{array}
}
