About This Chapter
Physical Science Fundamentals - Chapter Summary
This chapter digs into a variety of essential topics within the study of physical science, preparing you to apply knowledge of relevant terms, formulas, and processes. By the end of the chapter, you'll have bolstered your knowledge of motion, physical change, electricity, and all of the following:
- Classifying substances using their physical properties
- Simple machines
- Energy and energy transfer
The dashboard feature can be used as a way to stay organized throughout your studying. There, you can take a quick glance at your recent activity and progress through the content while exploring links to related practice quizzes and courses. Our subject-matter experts are also available for questions through the dashboard if you're feeling confused at any point of the chapter.
1. Classifying Substances by Their Physical Properties
After watching this video, you will be able to explain what physical properties are and use them to classify some common substances. A short quiz will follow.
2. Physical Change: Definition, Properties & Examples
Changes occur to substances every day. Some of them are natural, and some are caused by human beings. In this lesson, you will learn about physical changes and understand examples of these changes.
3. What Is Motion? - Definition & Equations
After watching this video, you will be able to explain what motion is and use basic equations of motion to solve problems. A short quiz will follow to test your knowledge.
4. What Is Gravity? - Definition & Equation
In this video, you'll learn about the force of gravity and why what goes up must also come down. You'll also learn about the equation for determining the gravitational force between two objects and the rate at which objects accelerate toward Earth.
5. What is Friction? - Definition, Formula & Forces
Friction is the force that opposes the motion of an object. Learn about the sources of friction, identify examples of friction and test your knowledge with quiz questions.
6. Laws of Inertia: Definition & Formula
Inertia is the tendency of an object to stay at rest or in motion. Learn more about Newton's first law as it explains how forces acting on an object are related to the object's mass and motion through several examples, and test your knowledge with quiz questions.
7. What Are Simple Machines? - Definition, Types & Examples
If you need to move or lift a heavy object, it would be wise to use a simple machine. Though these devices are far from fancy or high-tech, they are extremely helpful for getting work done.
8. Energy: Definition & Types
After completing this lesson, you will be able to explain what energy is, list various types of energy, and identify which type or types of energy are present in a situation.
9. Energy Transfer: Examples & Overview
Learn about energy and how the sun provides the energy needed to sustain life on Earth. Discover energy transfer and how energy is neither created nor destroyed, but moves from one place to another or changes from one form to another.
10. What is Light?
This lesson will define and describe what light is from both technical and more common-use perspectives, discuss what the different kinds of light are, and explain why it's called radiation.
11. What is Heat? - Definition & Explanation
In this lesson, you will learn the definition of heat and find out how it differs from temperature. You will also explore practical applications of heat such as expansion, thermodynamics, heat transfer, specific heat, phase transitions, and heat engines.
12. What Is Electricity? - Definition & Concept
Learn the history of electricity, from Ben Franklin's kite experiment to laptop batteries. Explore the many different ways electricity is measured, generated, and stored.
13. Magnetic Force: Definition, Poles & Dipoles
You're probably familiar with magnets, but have you ever stopped to consider how they work? In this lesson, we'll look at the root of magnetism and some of the fundamental properties of magnets.
