Ch 3: Glencoe Physical Science Chapter 3: Forces

About This Chapter

The Forces chapter of this Glencoe Physical Science Companion Course helps students learn the essential physical science lessons involving forces. Each of these simple and fun video lessons is about five minutes long and is sequenced to align with the Forces textbook chapter.

How It Works:

  • Identify the lessons in Glencoe Physical Science's Forces chapter with which you need help.
  • Find the corresponding video lessons within this companion course chapter.
  • Watch fun videos that cover the topics on forces that you need to learn or review.
  • Complete the quizzes to test your understanding.
  • If you need additional help, rewatch the videos until you've mastered the material or submit a question for one of our instructors.

Students will learn:

  • Newton's Second Law of Motion
  • The types of friction
  • Free fall acceleration and air resistance
  • The significance of the Law of Universal Gravitation

Newton's Second Law of Motion: The Relationship Between Force and Acceleration

1. Newton's Second Law of Motion: The Relationship Between Force and Acceleration

This lesson defines Newton's second law of motion. Examples are used to illustrate how unbalanced forces cause objects to accelerate. The examples are used to practice calculating acceleration and force for objects in motion.

Friction: Definition and Types

2. Friction: Definition and Types

You experience friction all the time, and you should be glad you do! Friction helps keep stationary objects in place as well as slow moving objects down as they slide across a surface. This lesson identifies what friction is and explains the two ways we find this force on earth.

Air Resistance and Free Fall

3. Air Resistance and Free Fall

Through experiments by Galileo and Newton, we can understand why all objects in free-fall experience the same acceleration, ''g''. We can also see why air resistance affects a falling object's velocity and how this can lead to a falling object reaching a terminal velocity.

The Law of Universal Gravitation: Definition, Importance & Examples

4. The Law of Universal Gravitation: Definition, Importance & Examples

Gravity is what pulls us toward Earth, but it's also what pulls Earth toward us. This is explained by the law of universal gravitation, which describes how all objects in the universe have this important force between them.

Isaac Newton's Formula for the Force of Gravity: Definition & Example

5. Isaac Newton's Formula for the Force of Gravity: Definition & Example

Watch this video lesson and you will see how you can calculate the force of attraction between two objects. Learn why our planets don't spin themselves out of orbit around the sun.

The Acceleration of Gravity: Definition & Formula

6. The Acceleration of Gravity: Definition & Formula

In this lesson, we will introduce the acceleration due to gravity. Objects in free fall are one of the few real world examples of straight line motion with constant acceleration, so they are commonly used when learning kinematics.

Projectile Motion: Definition and Examples

7. Projectile Motion: Definition and Examples

A projectile is any object that is given an initial velocity and then follows a path determined entirely by gravity. In this lesson, we will introduce projectile motion and touch on a few key facts to keep in mind when working through these problems.

Projectile Motion Practice Problems

8. Projectile Motion Practice Problems

After watching this video lesson, you will know how to use the sets of equations that are used to solve projectile motion problems. Learn how to manipulate them to find the answer you need.

Newton's Third Law of Motion: Examples of the Relationship Between Two Forces

9. Newton's Third Law of Motion: Examples of the Relationship Between Two Forces

This lesson describes Newton's third law of motion. Examples are provided to illustrate how interacting objects experience forces. The lesson explains how objects accelerate as a result of force. Applications of Newton's third law are illustrated in nature, machines, and space.

Linear Momentum: Definition, Equation, and Examples

10. 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.
