# Ch 6: Conservation of Energy & Momentum

### About This Chapter

## Conservation of Energy & Momentum - Chapter Summary

In this collection of lessons, you can study conservation of energy and momentum at your leisure. Move at your own pace as you study kinetic energy, potential energy and the conservation of mechanical energy. You can also review the law of conservation of momentum and pendulums in physics, and you'll have the chance to put your knowledge into action with a potential and kinetic energy lab. Once you complete this chapter, you should be able to:

- Detail the frequency and mass associated with a spring-block oscillator
- Analyze conservation of energy graphs
- Provide examples of conservation of energy in projectile motion
- Differentiate between conservation of linear momentum and conservation of angular momentum
- Explain the relationship between Newton's laws and the conservation of energy and momentum
- Discuss force vs. time and force vs. distance graphs
- Apply linear momentum formulas correctly
- Describe the parallel-axis theorem and the moment of inertia

Even if you've struggled with these topics before, you'll find our professionally designed lessons to be comprehensible. Work at your own pace and test yourself with the lesson quizzes. If you need any assistance along the way, one of our instructors is available to answer your questions through the Dashboard.

### 1. Kinetic Energy: Examples & Definition

To knock down a set of bowling pins, what must be true about the bowling ball? It must be moving! This lesson discusses the energy perspective of this simple truth: kinetic energy.

### 2. What is Potential Energy? - Definition & Examples

All great educators and parents inspire us to reach our potential - to discover parts of us yet to be realized. Potential energy in science is not much different. This lesson explores the concept of energy that has the potential to do work.

### 3. Conservation of Mechanical Energy

Energy comes in many forms and for any system can never be created or destroyed. This holds true for mechanical energy, which also obeys this law of conservation of energy. In this video lesson, you'll explore how mechanical energy is converted or transferred between forms and objects.

### 4. Potential and Kinetic Energy Lab

In this lab, we'll be studying the principle of conservation of energy. We'll use a ball to measure potential energy and kinetic energy and examine how the energy is converted from one form to another as the ball falls from a high place.

### 5. The Law of Conservation of Momentum

After completing this lesson, you will be able to explain what conservation of momentum is and use the equation for conservation of momentum to solve problems. A short quiz will follow.

### 6. Pendulums in Physics: Definition & Equations

After watching this lesson, you will be able to explain what a pendulum is, why it is an example of simple harmonic motion, and use equations to solve pendulum problems. A short quiz will follow.

### 7. Spring-Block Oscillator: Vertical Motion, Frequency & Mass

After watching this video, you will be able to explain how a spring-block oscillator is an example of simple harmonic motion. You will also be able to use an equation for a spring-block oscillator that relates the frequency and mass of the block.

### 8. Analyzing Conservation of Energy Graphs

In this lesson, we'll be learning how to use graphs to apply the law of conservation of energy to different situations in physics, such as a spring, pendulum, or a roller coaster.

### 9. Conservation of Energy in Projectile Motion: Examples & Analysis

A projectile moves through the air with only the force of gravity acting on it, so the total energy of the projectile doesn't change. In this lesson, learn more about how to apply the law of conservation of energy to projectile motion.

### 10. 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.

### 11. 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.

### 12. How Newton's Laws Relate to the Law of Conservation of Energy & Momentum

The many different topics under physics can be connected in ways you might not expect. Here you'll learn how Newton's second and third laws help us to derive conservation of energy and momentum.

### 13. Force vs. Time & Force vs. Distance Graphs

In this lesson, you'll find out how to determine impulse from a force-time graph and speed from a distance-time graph. You'll also learn how to describe the general shape of these graphs for simple harmonic motion.

### 14. Practice Applying Linear Momentum Formulas

Momentum is product of mass and velocity, and it is a quantity that is always conserved in collisions. In this lesson, we will dig deep into the concept of linear momentum, including practice working momentum problems.

### 15. 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.
