Newton’s Laws of Motion describe the behavior of objects under the influence of force.
- **Newton’s First Law (Law of Inertia)**: An object at rest stays at rest unless an external force is applied.
- **Newton’s Second Law**: F = ma (Force is mass times acceleration).
- **Newton’s Third Law**: "For every action, there is an equal and opposite reaction."
- **Applications**:
- Seat belts protect passengers by reducing inertia effects.
- Rockets work on Newton’s third law.
**Possible Exam Questions:**
1. Explain Newton’s three laws of motion with real-life examples.
2. Derive the formula F = ma from Newton’s second law.
3. How does the concept of inertia explain why passengers fall forward in a sudden stop?
4. Why do rockets move upward based on Newton’s third law?
5. Discuss practical applications of Newton’s laws in sports.
