- Students who struggle with learning disabilities or learning differences, including autism and ADHD
- Students who prefer multiple ways of learning physics (visual or auditory)
- Students who have missed class time and need to catch up
- Students who need an efficient way to learn about linear momentum
- Students who struggle to understand their teachers
- Students who attend schools without extra physics learning resources

Students Will Review:
This chapter helps students review the concepts in a linear momentum unit of a standard physics course. Topics covered include:
- Isolated systems
- Momentum and impulses
- Linear momentum equations
- Elastic and inelastic collisions
- Conserving linear momentum
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.
