### 1. 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.

### 2. Conservation of Angular Momentum

After watching this video you will be able to explain what is meant by conservation of angular momentum. You will also be able to use this concept along with the equation to solve problems. A short quiz will follow.

### 3. The Relationship Between Angular Momentum & Torque

In this lesson, we'll explore how torque and angular momentum affect objects in rotational motion. In doing this, we'll also discover the important relationship between torque and angular momentum.

### 4. Rolling Motion & the Moment of Inertia

After watching this lesson, you should be able to figure out the moment of inertia of an object as it rolls down a ramp and compare it to a theoretical value. A short quiz will follow.

### 5. Equilibrium: Translational & Rotational

Learn about the requirements for an object to be under translational or rotational equilibrium. Then work through a couple example problems that show how we can use translational and rotational equilibrium to find the forces acting on an object.

### 6. Torque: Concept, Equation & Example

After watching this lesson, you will be able to explain what torque is conceptually and mathematically and use both the equation and Newton's First Law for rotation to solve problems involving torque. A short quiz will follow.

### 7. Work & Power in Rotational Motion

After watching this lesson, you will be able to explain what work and power are in the context of rotational motion and use equations to solve problems involving rotational work and power. A short quiz will follow.

### 8. Linear vs. Rotational Velocity: Definitions & Equations

After completing this lesson, you will be able to explain the difference between linear and angular velocity, and use equations to calculate each of them. A short quiz will follow.

### 9. The Parallel-Axis Theorem & the Moment of Inertia

After watching this lesson, you will be able to explain what the parallel axis theorem is and how it is used. You will also be able to use the theorem to solve problems. A short quiz will follow.
