System of Particles and Rotational Motion

Subject: General Science

Book: NCERT Science Class 11

Objects in rotational motion follow specific principles.
- **Center of Mass**:
- The point at which the mass of a system is considered to be concentrated.
- **Moment of Inertia**:
- Resistance to rotational motion.
- **Torque**:
- Rotational force (Torque = Force × Perpendicular Distance).
- **Angular Momentum**:
- L = Iω (Product of moment of inertia and angular velocity).

**Possible Exam Questions:**
1. What is the difference between linear and rotational motion?
2. Define torque and its importance in rotational motion.
3. Explain the concept of moment of inertia.
4. How is angular momentum conserved?
5. Discuss the application of rotational motion in daily life.
