Which of the following statement is not correct for an object moving along a straight path in an accelerated motion?

Options

A. Its speed keeps changing
B. Its velocity always changes
C. It always goes away from the earth
D. A force is always acting on it

Explanation

To determine which statement is not correct for an object moving along a straight path in accelerated motion, let's analyze each option step by step.

### Step 1: Understanding Accelerated Motion
Accelerated motion means that the object is experiencing a change in velocity over time. This change can be due to a change in speed, direction, or both.

### Step 2: Analyzing the Statements
1. **Its speed keeps changing**:
- In accelerated motion, the speed of the object can change. This statement is correct.

2. **Its velocity always changes**:
- Velocity is a vector quantity that includes both speed and direction. If an object is accelerating, its velocity will change. This statement is also correct.

3. **It always goes away from the Earth**:
- This statement implies a specific direction of motion. An object in accelerated motion can move in any direction, including towards the Earth, away from the Earth, or horizontally. Therefore, this statement is not correct.

4. **A force is always acting on it**:
- According to Newton's second law, if an object is accelerating, there must be a net force acting on it. This statement is correct.

### Conclusion
The statement that is not correct for an object moving along a straight path in accelerated motion is **"It always goes away from the Earth."**

### Final Answer
**The incorrect statement is: "It always goes away from the Earth."**
