The question presented asks whether the centripetal force does work on an object undergoing uniform circular motion (with constant speed). Here's a breakdown of the correct answer based on the principles of physics:

1. **Centripetal Force and Work**: In uniform circular motion, the centripetal force always acts **perpendicular** to the direction of the object's motion (which is tangential). Work is defined as the force applied on an object in the direction of its displacement. Since the centripetal force is perpendicular to the displacement (which is tangential), **no work is done** by the centripetal force. This is because work is the product of the force component in the direction of motion and the displacement.

2. **Explanation**:
   - **"Yes, work being done is a requirement for circular motion"**: This is incorrect. Work is not required to maintain circular motion; the force just needs to change the direction of the velocity.
   - **"Since a moving object is experiencing a force, the work done cannot be zero"**: Incorrect. A force acting on an object does not necessarily mean work is done. As explained earlier, work is only done if the force has a component in the direction of motion.
   - **"The centripetal force does no work because it is perpendicular to the object's motion"**: This is the correct answer. Since the centripetal force is perpendicular to the displacement, no work is done.
   - **"Yes, the centripetal force accelerates the object and thus does (non-zero) work"**: Incorrect. While the centripetal force changes the direction of velocity (causing centripetal acceleration), it does not do work because it does not change the speed of the object (which remains constant).
   - **"The centripetal force does no work on the object because the object is not accelerating"**: This is incorrect because the object is indeed accelerating (centripetal acceleration), even though its speed is constant.

### Correct Answer(s):
- **"The centripetal force does no work because it is perpendicular to the object's motion"**

Do you have any questions, or would you like a further explanation?

Here are five relative questions to explore this concept:
1. What is the mathematical formula for work in physics?
2. How does centripetal acceleration relate to the force in circular motion?
3. What role does friction play in non-uniform circular motion?
4. How does angular velocity differ from linear velocity in circular motion?
5. What happens to an object if the centripetal force is suddenly removed?

**Tip**: Remember that the direction of force and motion are key in determining if work is done!

An object is undergoing uniform circular motion ('uniform' means constant speed). Consider whether the centripetal force does work on the object (and why or why not?). Select one or more answers.

Understand whether the centripetal force does work on an object in uniform circular motion. This problem explores key physics concepts such as centripetal force, work-energy principles, and their relation to circular motion.
