About This Chapter
Linear Momentum - Chapter Summary and Learning Objective
The lessons in this chapter will introduce the laws of linear momentum. Through instruction and real world examples, you'll become familiar with linear momentum and how it works. Other lessons deal with the physics of collisions and explore topics such as the impulse-momentum change equation. By the time you've finished this chapter, you should have a solid understanding of:
- How to solve equations for momentum
- The momentum conservation principle
- The definition of elastic and inelastic collisions
- How to evaluate collisions in isolated systems
- Center of mass and center of gravity
|Linear Momentum: Definition, Equation, and Examples||In this lesson, we'll look at what linear momentum is and learn how to solve momentum equations.|
|Momentum and Impulse: Definition, Theorem and Examples||You'll learn about the physics of collisions and how they relate to the laws of momentum. You'll also learn about the impulse-momentum change equation and study examples.|
|Conservation of Linear Momentum: Formula and Examples||Here, you can learn to use the momentum conservation principle with various examples.|
|Elastic and Inelastic Collisions: Difference and Principles||This lesson explores inelastic and elastic collisions and demonstrates that momentum is conserved in both.|
|Isolated Systems in Physics: Definition and Examples||We'll examine isolated systems and how to determine if a collision takes place in an isolated system.|
|Center of Mass and Center of Gravity: Definition and Equation||Learn what center of mass and the center of gravity are and how to find them.|
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.
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.
