When an object is thrown up , the force of gravity

Options

A. acts in the direction of the motion
B. acts in the opposite direction of the motion
C. remains constant as the body moves up
D. increases as the body moves up

Answer

To solve the question regarding the force of gravity when an object is thrown upwards, let's analyze the situation step by step.

### Step-by-Step Solution:

1. **Understanding the Scenario**:
- When an object is thrown upwards, it initially moves in the upward direction. We need to analyze the forces acting on the object during this motion.

2. **Identifying the Force of Gravity**:
- The force of gravity always acts towards the center of the Earth. This means that regardless of the object's motion (upwards or downwards), the gravitational force will always point downwards.

3. **Direction of Motion**:
- When the object is thrown upwards, its motion is in the upward direction. However, the gravitational force acts in the opposite direction, which is downwards.

4. **Effect of Gravity on the Object**:
- As the object moves upwards, the gravitational force acts downwards, opposing the motion. This means that the object's upward velocity will decrease due to the gravitational pull until it reaches its maximum height (where its velocity becomes zero).

5. **Conclusion**:
- Since the gravitational force acts in the opposite direction to the motion of the object when it is thrown upwards, the correct answer to the question is:
- **Option 2: Acts in the opposite direction of the motion**.
