Module 5 - Collisions
In This Module
You will learn about the mathematics and characteristics of different kinds of collisions.
You will complete the following lessons in this module.
Lesson 1__ Momentum and Impulse
Lesson 2__ Forces and Newton's Third Law
Lesson 3__Conservation of momentum
Lesson 4__Designing a Helmet
Big Picture
Big Picture
The collision of objects occurs constantly at a microscopic and macroscopic level. These collision can be analyzed in terms of the orientation of the objects involved in the collision and by the quantities conserved in the collision. In this module we will be looking at a few different types of collisions and learning how to do a vector analysis of object involved in collisions.
Module 5 Inquiry
- What is a linear collision ?
- How does Newton's third law affect colliding objects ?
- How can we use mathematics to analyze collisions ?
- How do the physics of collisions affect the design of safety equipment ?
Lesson 2.5.1
Lesson 1- Momentum and Impulse
Get Focused
Momentum is a vector quantity that is involved when objects interact with one another. In this lesson we will learn about momentum, and changes is momentum (impulse)
Consider the following essential questions as you complete Lesson 1:
- What is momentum ?
- What is Impulse ?
- What physical quantities affect momentum and/or impulse

Lesson Summary
In this lesson we learned about momentum and impulse.
Lesson 2 will look at the connection between momentum and Newton's Third Law.
Lesson 2.5.2
Lesson 2 — Forces and Newton's Third Law
Get Focused
When objects react with one another there are action and reaction forces that act on the objects. In this lesson we will investigate how action and reaction forces related to the momentum of objects involved in a collision.
Consider the following essential questions as you complete Lesson 4:
- What is an action force ?
- What is a reaction force ?
- How does momentum related to Newton's Third Law

Module 5 : Lesson 2 Assignment.
Once you have completed all of the learning activities for this lesson, you can complete the online assignment.
Lesson Summary
In this lesson you discovered the relationship between Newton's Third Law and momentum.
Lesson 3 will look at the Law of Conservation of Momentum.
Lesson 2.5.3
Lesson 3 - Conservation of Momentum
Get Focused
The Law of Conservation of Momentum is one of the fundamental laws of physics. In this lesson we will investigate how to use the Law of Conservation of Momentum to calculate the momentum and/or velocity of objects involved in a collision.
Consider the following essential questions as you complete Lesson 3:
- What does the Law of Conservation of Momentum state ?
- What is a closed system ?
- Does the Law of Conservation of Momentum apply in all directions simultaneously

Module Summary and Assessment
Module Summary and Assessment
The conservation of momentum is a fundamental principle of physics that can be used to predict the actions of colliding objects. We can use this information to design various types of safety equipment that reduce the amount of force acting on people experiencing a collision of some sort by increasing the time in which the force is experienced. Many devices such as helmets, air bags, and gymnastics mats operate on this principle.
Module Assessment
In this module you should have completed :
This is the last module in the unit. You should now be able to complete the unit 2 quiz and the unit 2 exam for the unit.
Unit 2 Conclusion
In this unit you have investigated Newton's first, second and third laws of motion as well as the law of conservation of motion. We have used our knowledge of these laws to discover the magnitude and direction of vector quantities for various scenarios including stopping distances. We also used displacement time graphs and velocity time graphs to discover information about moving objects using slope and area calculations.
