The document you uploaded is a Grade 12 Physical Science practical task focused on the conservation of momentum. It includes two main sections:

1. **Section A: Practical Experiment (25 Marks)** - This part requires watching a video demonstrating the conservation of momentum using trolleys. Questions include identifying experiment variables, interpreting data, and verifying if momentum is conserved. You are asked to complete tables, calculate momentum, and discuss possible experimental errors.

2. **Section B: Application Questions (25 Marks)** - This part applies momentum principles to hypothetical scenarios. It includes calculations for velocity, momentum, and force in situations such as a brake failure scenario involving water barrels to reduce a car's momentum safely.

If you'd like, I can help you understand or solve specific questions from this task. Let me know where you'd like to start!

Here are five follow-up questions to deepen your understanding of momentum and its conservation:

1. Why is momentum conserved in a closed system, and what role does friction play?
2. How can conservation of momentum be verified without directly measuring time?
3. What are some common sources of error in practical momentum experiments, and how can they be minimized?
4. How is impulse related to the change in momentum during a collision?
5. Why is it important to convert measurements to SI units in physics experiments?

**Tip:** Remember to always carefully convert units, especially in momentum and force calculations, to avoid common mistakes and ensure accuracy.
