About This Chapter
Fundamentals of Linear Momentum - Chapter Summary
This chapter includes lessons on the fundamentals of linear momentum. Use these brief but informative lessons to review linear momentum, elastic collisions, and more. After completing the chapter, you should be ready to:
- Define linear momentum and explain the factors that can affect the momentum of an object
- Understand how impulse relates to momentum
- Detail the law of conservation of momentum
- Explain the difference between elastic and inelastic collisions
- Understand the principles that govern rocket propulsion
Our expert instructors can help you quickly get up to speed on linear momentum. If you need help with any of the lesson topics, you can submit questions to them using your personal Dashboard. The Dashboard can also be used to track your progress through the chapter.
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. Rocket Propulsion: Definition & Principles
Rockets and traveling to space has long been a fascinating subject for young and seasoned minds alike. In this lesson, you will get an overview of rocket propulsion, and learn some of its principles, concepts, and terms.
