Linear Momentum Principles - Videos & Lessons

About This Chapter

Check out these lessons on momentum, impulse and isolated systems. Videos and quizzes also cover the conservation of momentum in elastic and inelastic collisions.

Linear Momentum Principles - Chapter Summary

Use this chapter to study the relationship between mass, velocity and momentum. You can also review methods for measuring changes in momentum and apply the law of conservation of momentum to elastic and inelastic collisions. You'll even get practice finding unknown values when presented with variables for both collision types.

To wrap up your study of linear momentum, check out lessons covering the characteristics of isolated systems and the differences between the center of mass and the center of gravity. Topics of instruction include:

Linear momentum and impulse
Conservation of linear momentum
Elastic and inelastic collisions
Isolated systems
Center of mass
Center of gravity

This chapter's video lessons include fun illustrations as well as practice problems to help you remember important linear momentum concepts. You'll also find transcripts if you'd prefer a written format, as well as multiple-choice quizzes to give you extra problem-solving opportunities. Our experienced instructors are also available to answer any question you might have about these linear momentum topics.

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. 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.

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. 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.
