About This Chapter
AP Physics 2: Conservation of Linear Momentum - Chapter Summary
Our instructors present the conservation of linear momentum and other physics topics, including elastic and inelastic collisions and common final velocity, in this engaging chapter. You don't have to be intimidated by challenging subjects with these self-paced and professionally written lessons. Review the material as many times as you need to, and then take the multiple-choice quizzes to make sure you understand before moving on. If at any time you get stuck when working through the chapter, feel free to contact one of our instructors for help. Once you complete these lessons, you should be ready to:
- Give the formula for conservation of linear momentum
- Define isolated systems as they're used in physics
- Detail the principles associated with elastic and inelastic collisions
- Analyze inelastic and elastic collisions
- Describe conservation of kinetic energy
- Determine common final velocity in inelastic collisions
- Explain conservation of momentum in 1-D and 2-D systems
1. 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.
2. 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.
3. 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.
4. 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.
5. Conservation of Kinetic Energy
Kinetic energy is the energy of motion. In this lesson, we investigate how kinetic energy is sometimes conserved and sometimes not conserved, based on the type of collisions between masses.
6. Common Final Velocity in Inelastic Collisions
When two objects collide and stick together, this is called an inelastic collision. In this lesson, learn how to recognize inelastic collisions and how to use conservation of momentum to find the common final velocity.
7. Conservation of Momentum in 1-D & 2-D Systems
Momentum is the resistance to the change in velocity, and momentum is always conserved in any collision or explosion. This lesson will explore the conservation of momentum for multiple masses colliding in one and two dimensions, and for a single mass exploding.
