Ch 9: Conservation Laws in Astronomy: Help and Review

About This Chapter

The Conservation Laws in Astronomy chapter of this Intro to Astronomy Help and Review course is the simplest way to master conservation laws in astronomy. This chapter uses simple and fun videos that are about five minutes long plus lesson quizzes and a chapter exam to ensure students learn the essentials of the topic.

Who's it for?

Anyone who needs help learning or mastering Intro to Astronomy material will benefit from taking this course. There is no faster or easier way to learn introductory astronomy. Among those who would benefit are:

  • Students who have fallen behind in understanding conservation laws in astronomy
  • Students who struggle with learning disabilities or learning differences, including autism and ADHD
  • Students who prefer multiple ways of learning science (visual or auditory)
  • Students who have missed class time and need to catch up
  • Students who need an efficient way to learn about conservation laws in astronomy
  • Students who struggle to understand their teachers
  • Students who attend schools without extra science learning resources

How it works:

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.

What is Energy? - Definition and Significance in Nature

3. What is Energy? - Definition and Significance in Nature

This lesson describes the nature of energy and how it is transferred from one source into another. Additionally, it will describe the significance of energy in natural systems.

Kinetic Energy to Potential Energy: Relationship in Different Energy Types

4. Kinetic Energy to Potential Energy: Relationship in Different Energy Types

This video defines and describes kinetic and potential energy. You'll learn how different types of energy can be classified as potential and kinetic. You'll also find out how kinetic and potential energy are transformed.

What is Mechanical Energy? - Definition & Examples

5. What is Mechanical Energy? - Definition & Examples

In physics, energy is how work gets done. This video describes one important type of energy, mechanical energy, and provides examples of both kinetic and potential mechanical energy.

Conservation of Mechanical Energy

6. 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.

What is Thermal Energy? - Definition & Examples

7. What is Thermal Energy? - Definition & Examples

This lesson defines and identifies examples of thermal energy everywhere from your kitchen to the Earth's core. We'll discuss geothermal energy, a renewable energy source, as well.

Temperature Units: Converting Between Kelvins and Celsius

8. Temperature Units: Converting Between Kelvins and Celsius

Have you ever wondered what the lowest possible temperature is? In this lesson, you will learn what temperature measures. You will also be introduced to the Kelvin scale (an absolute scale) and learn how it relates to the Celsius scale.

Changes in Heat and Energy Diagrams

9. Changes in Heat and Energy Diagrams

Did you know that temperature and heat are not the same thing? Did you know that the temperature of water doesn't change when it boils? This lesson describes the relationship between heat and temperature. Diagrams are used to illustrate the relationship between heat and temperature during phase changes.

Atmospheric Pressure: Definition & Effects

10. Atmospheric Pressure: Definition & Effects

Atmospheric pressure is around us all of the time. The air you are breathing has weight, and although it doesn't weigh a lot, there is a lot of it around. This lesson will cover atmospheric pressure and its effects.
