The horizontal distance travelled by a projectile is called its

Options

A. trajectory
B. range
C. amplitude
D. none of these

Answer

To solve the question regarding the horizontal distance traveled by a projectile, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Projectile Motion**:
- A projectile is an object that is thrown into the air with an initial velocity and follows a curved path under the influence of gravity.

2. **Identifying the Terms**:
- In the context of projectile motion, we need to identify the correct term for the horizontal distance traveled by the projectile. The options given are:
- A) Trajectory
- B) Range
- C) Amplitude
- D) None of these

3. **Defining the Terms**:
- **Trajectory**: This refers to the path that a projectile follows during its motion. It is not specifically the horizontal distance.
- **Range**: This is defined as the horizontal distance traveled by the projectile from the point of launch to the point where it lands.
- **Amplitude**: This term is not applicable in the context of projectile motion.

4. **Conclusion**:
- Based on the definitions, the correct term for the horizontal distance traveled by a projectile is **Range**.

5. **Final Answer**:
- Therefore, the answer to the question is **Option B: Range**.
