Identify the type of friction in each image: air resistance or water resistance.

Let's analyze each image and determine whether the friction shown is air resistance or water resistance.

1. Person riding a bicycle

- The cyclist is moving through the air.
- As the bike moves forward, it pushes against the air, which creates air resistance.
- This is a classic example of air resistance (also called drag).
✔ Answer: AIR RESISTANCE

2. Parachutist descending with a parachute

- The parachute is open and slowing the person’s fall through the air.
- The large surface area of the parachute increases air resistance, which slows the descent.
✔ Answer: AIR RESISTANCE

3. Speedboat moving on water

- The boat is traveling on the surface of the water.
- It pushes against the water, creating splashes and waves.
- The force opposing its motion is due to water resistance (also known as hydrodynamic drag).
✔ Answer: WATER RESISTANCE

---

4. Shark swimming in water

- The shark is underwater, moving through the water.
- Its streamlined body helps reduce water resistance, but it still experiences this type of friction.
✔ Answer: WATER RESISTANCE

---

✔ Final Answers:

1. Bicycle rider → AIR RESISTANCE
2. Parachutist → AIR RESISTANCE
3. Speedboat → WATER RESISTANCE
4. Shark → WATER RESISTANCE

You can fill in the boxes accordingly:

- First box (bicycle): AIR RESISTANCE
- Second box (parachute): AIR RESISTANCE
- Third box (boat): WATER RESISTANCE
- Fourth box (shark): WATER RESISTANCE

🔍 Explanation:

- Air resistance occurs when an object moves through the air.
- Water resistance occurs when an object moves through water.
- Both are types of fluid friction, depending on the medium (air or water).
