# Grade 9 Science Module: Impulse and Momentum

This Self-Learning Module (SLM) is prepared so that you, our dear learners, can continue your studies and learn while at home. Activities, questions, directions, exercises, and discussions are carefully stated for you to understand each lesson.

Each SLM is composed of different parts. Each part shall guide you step-by-step as you discover and understand the lesson prepared for you.

Pre-tests are provided to measure your prior knowledge on lessons in each SLM. This will tell you if you need to proceed on completing this module or if you need to ask your facilitator or your teacherâ€™s assistance for better understanding of the lesson. At the end of each module, you need to answer the post-test to self-check your learning. Answer keys are provided for each activity and test. We trust that you will be honest in using these.

Please use this module with care. Do not put unnecessary marks on any part of this SLM. Use a separate sheet of paper in answering the exercises and tests. And read the instructions carefully before performing each task.

Have you ever experience riding a motorcycle or a car on a muddy road? What do you observe about the speed of the motorcycle/car? Did it slow down or speeds up? Have you seen vehicular collisions in movies or even witness it in real life? In this lesson, we will know the science concepts behind it.

In this module, you will learn about the principles applied to collision of objects which includes the following lessons:

• Lesson 1: Impulse and Momentum
• Lesson 2: Relationship of Impulse and Momentum to Collisions of Objects

At the end of this module, you should be able to:

1. Relate impulse and momentum to collision of objects (e.g., vehicular collision).
