About This Chapter
Understanding Linear Momentum - Chapter Summary
Use this chapter to increase your knowledge of linear momentum in physics. Discover the ways in which size and speed affect momentum, and explore the correlation between acceleration and momentum. Chapter highlights include the law of conservation of momentum, Newton's laws of motion and the characteristics of elastic and inelastic collisions. Watching these videos could help you with:
- Learning about momentum equations
- Discovering the effects of impulse on momentum
- Exploring examples of the conservation of linear momentum
- Examining the conservation of momentum in elastic and inelastic collisions
- Defining isolated systems
Study these topics as you strive to boost your physics knowledge. The short video lessons are animated and informative. Watch them online anytime via your mobile device. Written transcripts and five-question quizzes are included in the chapter. The Dashboard area records your recent activities and helps you monitor your progress.
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. 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.
