Wind is always associated with :

Options

A. kinetic energy
B. chemical energy
C. potential energy
D. gravitational energy

Answer

To solve the question "Wind is always associated with:", we can follow these steps:

### Step 1: Understand the nature of wind
Wind is the movement of air from one place to another, which is caused by differences in air pressure.

**Hint:** Think about what makes wind move and how we can measure its strength.

### Step 2: Identify the types of energy
We have four options to consider:
1. Kinetic energy
2. Chemical energy
3. Potential energy
4. Gravitational energy

**Hint:** Consider what kind of energy is related to motion.

### Step 3: Analyze the relationship between wind and energy
Wind is associated with the motion of air. The energy associated with motion is called kinetic energy. The faster the wind blows, the more kinetic energy it has.

**Hint:** Recall the definition of kinetic energy and how it relates to speed.

### Step 4: Eliminate the other options
- **Chemical energy** is related to the energy stored in chemical bonds, which is not relevant to wind.
- **Potential energy** is related to the position of an object in a gravitational field, which does not apply to the movement of air.
- **Gravitational energy** also pertains to the position of an object in a gravitational field, not the motion of air.

**Hint:** Think about what each type of energy represents and whether it applies to wind.

### Step 5: Conclude with the correct option
Since wind is associated with motion and the energy of motion is kinetic energy, the correct answer is option 1: kinetic energy.

**Final Answer:** Wind is always associated with kinetic energy.
