Module 1—Momentum and Impulse

In This Module

 

Lesson 1—Momentum and Newton’s Second Law

 

In this lesson you will define the vector quantity momentum and its relationship to Newton’s laws and address what we really mean when we say “speed kills.” To do this, you will explore the following questions:

• What is momentum?

• Why is momentum defined as a vector?

• How is momentum related to Newton’s laws?

Lesson 2—Impulse: Changing Momentum

 

In this lesson you will explore how it is possible to reduce injury and death when a vehicle occupant experiences a large change in momentum during a collision through the function of vehicle safety features. To better understand this, you will explore the concept of momentum and its relationship to Newton’s second law. In this lesson you will explore the working principles of safety devices in the context of the following questions:

• What is impulse?

• How is impulse related to a change in momentum?

• How is impulse related to Newton’s laws?
