Ch 6: Holt Physical Science Chapter 6: Forces and Motion

About This Chapter

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

How it works:

  • Identify the lessons in the Holt Physical Science Forces and Motion chapter with which you need help.
  • Find the corresponding video lessons within this companion course chapter.
  • Watch fun videos that cover the forces and motion topics 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:

  • The acceleration of gravity
  • Air resistance and free fall
  • Projectile motion
  • Newton's Laws of Motion
  • Linear momentum

9 Lessons in Chapter 6: Holt Physical Science Chapter 6: Forces and Motion
The Acceleration of Gravity: Definition & Formula

1. 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.

Air Resistance and Free Fall

2. 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.

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

3. 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.

Projectile Motion: Definition and Examples

4. 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.

Newton's First Law of Motion: Examples of the Effect of Force on Motion

5. Newton's First Law of Motion: Examples of the Effect of Force on Motion

This lesson describes Newton's first law of motion, also known as the law of inertia. The interaction between force and motion is explained. Several examples are used to discuss the implications of this law on earth and in space.

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

6. 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.

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

7. 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

8. 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

9. 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.
