### About This Chapter

## AP Physics 1: Linear Momentum - Chapter Summary and Learning Objectives

Video lessons in this chapter can help you explore topics ranging in complexity from the variables involved in calculating momentum to the relationship between Newton's laws and the physics of collisions. You can also learn the impulse-momentum change equation used to determine the amount of force acting on an object or measure the resulting change in speed. Instructors include plenty of examples, illustrations and sample problems to help you learn these physics principles. By the end of this chapter, you should be able to do the following:

- Explain the relationship between momentum, mass and velocity
- Apply basic physics principles to collisions
- Differentiate between collision types
- Define an isolated system

### 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. 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.

### 3. Conservation of Linear Momentum: Formula and Examples

The law of conservation of momentum tells us that the amount of momentum for a system doesn't change. In this lesson, we'll explore how that can be true even when the momenta of the individual components does change.

### 4. 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.

### 5. Elastic Collisions in One Dimension

In this lesson, you'll learn how to solve one-dimensional elastic collision problems. You'll find that understanding the conservation of momentum and conservation of kinetic energy is essential to solving these types of problems.

### 6. Isolated Systems in Physics: Definition and Examples

Systems are important to understand when studying physics, but they are not always easy to describe. In this video lesson, you'll identify isolated systems and understand what makes them unique.

### 7. Calculating Center of Mass: Definition, Equation & Example

What is the center of mass and how is it calculated? Is it the same as the centroid or center of gravity? Learn how to find the center of mass of objects in one-, two-, even three-dimensional space!

### 8. Calculating the Velocity of the Center of Mass

The center of mass concept is very useful when dealing with a system of particles. In this lesson, we deal with the velocity of the center of mass and how to determine if it changes, causing a net acceleration.
