Test your knowledge with a 30-question chapter practice test
Linear Momentum: Definition, Equation, and Examples

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.

Conservation of Linear Momentum: Formula and Examples

2. 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.

Angular Momentum vs. Linear Momentum

3. Angular Momentum vs. Linear Momentum

After watching this lesson, you will be able to explain the difference between angular and linear momentum and solve problems using angular momentum equations. A short quiz will follow.

Elastic and Inelastic Collisions: Difference and Principles

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.

Isolated Systems in Physics: Definition and Examples

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.

Understanding the Center of Mass & Center of Gravity

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.
