# Ch 9: Linear Momentum

### About This Chapter

## Linear Momentum - Chapter Summary

For an overview of linear momentum in physics, check out this online study resource. Inside the chapter, you'll find short lessons that explain concepts and formulas related to linear momentum, impulse, elastic collisions and more. Following each lesson is a short quiz to help you retain the terms and topics you've studied. The flexible online format of the chapter allows you to study whenever and wherever it's convenient. Upon completion of the chapter, you'll be equipped to:

- Define linear momentum
- Understand how impulse effects the momentum of an object
- Explain what the law of conservation says about linear momentum
- Differentiate between elastic and inelastic collisions

### 1. Linear Momentum: Definition, Equation, and Examples

Any moving object has momentum, but how much momentum it has depends on its mass and velocity. In this lesson, you'll identify linear momentum, as well as see examples of how an object's momentum is affected by mass and velocity.

### 2. Elastic and Inelastic Collisions: Difference and Principles

When objects come in contact with each other, a collision occurs. In this lesson, you'll learn about the two types of collisions as well as how momentum is conserved in each.

### 3. Practice Applying Conservation of Linear Momentum

Momentum is a vector and is the product of mass and velocity. In this lesson, we will work through one-dimensional and two-dimensional momentum problems.

### 4. Analyzing Elastic & Inelastic Collisions

In this lesson, you'll have the chance to explore the differences between elastic and inelastic collisions, and use that knowledge to solve problems. Lesson topics will include equations and theories related to momentum.

### 5. Practice Applying Linear Momentum Formulas

Momentum is product of mass and velocity, and it is a quantity that is always conserved in collisions. In this lesson, we will dig deep into the concept of linear momentum, including practice working momentum problems.

### 6. Impulse: Definition, Equation, Calculation & Examples

In this lesson you will learn about the concept of impulse and how you can apply it to a variety of interesting situations. You will learn about the relationship between impulse and momentum and how to calculate impulse through a variety of examples.

### 7. Momentum and Impulse: Definition, Theorem and Examples

To understand how a change in momentum affects an object, we look to impulse. In this lesson, you'll understand how impulse describes an object's change in momentum, as well as how changing the force or time of the impulse can have very different outcomes.

### 8. Linear Momentum, Impulse & Energy Conservation

In this lesson, you'll learn about linear momentum, impulse, and energy conservation. These are all important components of collisions, which can be large, small, and everything in between!
