Ch 8: AP Physics C: Linear Momentum

About This Chapter

Watch online science video lessons and learn about momentum, impulse, isolated systems and more. These lessons are just a portion of our AP Physics C course.

AP Physics C: Linear Momentum - Chapter Summary

You might not have counted on discussing car crashes over the course of your physics studies, but the lessons in this chapter on linear momentum do just that. Watch the short entertaining videos included here to discover whether these types of accidents are examples of inelastic or elastic collisions and find out what happens to an object's speed and velocity upon impact. This chapter is designed to prepare you in these areas of the AP Physics C exam:

  • Defining linear momentum
  • Describing the relationship between linear momentum and impulse
  • Explaining the conservation of momentum
  • Discussing the generation of heat in elastic and inelastic collisions
  • Defining isolated systems
  • Identifying differences between the center of mass and the center of gravity
  • Calculating center of mass

Linear Momentum: Definition, Equation, and Examples

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.

Momentum and Impulse: Definition, Theorem and Examples

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.

Conservation of Linear Momentum: Formula and Examples

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.

Elastic and Inelastic Collisions: Difference and Principles

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.

Isolated Systems in Physics: Definition and Examples

5. 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.

Understanding the Center of Mass & Center of Gravity

6. Understanding the Center of Mass & Center of Gravity

After watching this video, you will be able to explain the difference between center of mass and center of gravity and give examples of situations where they would be different. A short quiz will follow.

Calculating Center of Mass: Definition, Equation & Example

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!
