### 1. Introduction
- Briefly introduce the concept of momentum and its conservation during collisions.
- Discuss the significance of studying elastic and inelastic collisions in understanding physical systems.

### 2. Objectives
- To investigate the conservation of momentum in both elastic and inelastic collisions.
- To analyze the relationship between mass, velocity, and momentum.

### 3. Background Theory
- Define momentum (\( p \)) and its formula: \( p = mv \) (where \( m \) is mass and \( v \) is velocity).
- Explain the law of conservation of momentum: The total momentum of a closed system remains constant if no external forces act on it.
- Differentiate between elastic and inelastic collisions:
- **Elastic Collision**: Kinetic energy and momentum are conserved.
- **Inelastic Collision**: Momentum is conserved, but kinetic energy is not.

### 4. Equipment and Materials
- List all the materials and equipment used during the experiment, such as:
- Collision cart
- Masses (weights)
- Track
- Stopwatch
- Measuring tape
- Logger or sensor (if using technology)

### 5. Procedure
- Step-by-step instructions on how the experiment was conducted. Include:
- Setting up the track and carts.
- Measuring the masses of the carts used.
- Performing a series of collisions (both elastic and inelastic).
- Measuring initial and final velocities.
- Repeating trials for accuracy.

### 6. Data Collection
- Create tables to present your raw data:
- **Table 1**: Mass and velocity data for each cart.
- **Table 2**: Data before and after collisions (include initial and final velocities for each trial).

### 7. Analysis and Calculations
- Use the data gathered to calculate momentum before and after each collision.
- Show calculations step-by-step:
- Calculate total momentum before the collision.
- Calculate total momentum after the collision.
- Compare initial and final momentum to evaluate conservation.
- Graphs or charts can be helpful to visualize data, especially to show relationships between mass, velocity, and momentum.

### 8. Conclusion
- Summarize the findings of the lab.
- Discuss whether the experimental results supported the principle of conservation of momentum.
- Reflect on any discrepancies, possible sources of error, and suggestions for improving future experiments.

### 9. References
- List any textbooks, websites, or articles referenced during the preparation of the lab report.

### Formatting Tips
- Use diagrams and illustrations where appropriate to enhance understanding.
- Ensure clarity and precision in your writing.
- Proofread your report for grammatical accuracy and coherence.

This structure will help you create a comprehensive lab portfolio that demonstrates your understanding of momentum and collisions in physics. Good luck with your project!
