A. C
B. B
C. A
D. D

Answer

To solve the question about the motion of a spinning top, we need to analyze the forces involved in its motion.

1. **Understanding the Motion of a Spinning Top**:
A spinning top rotates around its axis. As it spins, it experiences forces that keep it in motion.

**Hint**: Think about what keeps the top stable while it spins.

2. **Identifying the Forces**:
The forces acting on a spinning top include:
- **Centripetal Force**: This is the force that acts on an object moving in a circular path, directed towards the center of the circle.
- **Centrifugal Force**: This is a perceived force that acts outward on a body moving around a center, arising from the body's inertia.
- **Gravitational Force**: This is the force of attraction between two masses, such as the Earth and the top.
- **Frictional Force**: This is the force that opposes the motion of two surfaces in contact.

**Hint**: Consider which of these forces is responsible for maintaining the circular motion of the top.

3. **Analyzing the Options**:
- **Centripetal Force**: This is the key force that keeps the top spinning in a circular motion. It acts towards the center of the circular path.
- **Centrifugal Force**: This is not a real force but rather a result of inertia when observing from a rotating frame.
- **Gravitational Force**: While it acts on the top, it does not directly relate to the spinning motion.
- **Frictional Force**: This is involved when the top spins against the surface but is not the primary force responsible for its spinning motion.

**Hint**: Focus on which force is essential for circular motion.

4. **Conclusion**:
The motion of a spinning top is primarily an example of **Centripetal Force** because this force is necessary to keep the top rotating around its axis.

**Final Answer**: A. Centripetal Force
