Ch 2: Holt McDougal Physics Chapter 2: Motion in One Dimension

About This Chapter

The Motion in One Dimension chapter of this Holt McDougal Physics Companion Course helps students learn the essential physics lessons of one-dimensional motion. Each of these simple and fun video lessons is about five minutes long and is sequenced to align with the Motion in One Dimension textbook chapter.

How It Works:

  • Identify the lessons in the Holt McDougal Motion in One Dimension chapter with which you need help.
  • Find the corresponding video lessons within this companion course chapter.
  • Watch fun videos that cover the one-dimensional 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 relationship between motion and velocity
  • The meaning of displacement and distance
  • The difference between speed and velocity
  • The definition of acceleration
  • How to determine the acceleration of an object
  • How velocity vs. time graphs are used
  • The difference between time and velocity
  • The formula to the acceleration of gravity
  • The Big Five kinematics equations
  • The relationship between free fall and air resistance
  • How to solve free fall physics problems

State of Motion and Velocity

1. State of Motion and Velocity

An object's state of motion describes how it is moving. But there are many ways we can describe motion, such as speed and velocity. This motion is relative to other objects around it, such as the earth, the sun, and even other stars in our galaxy.

Distance and Displacement in Physics: Definition and Examples

2. Distance and Displacement in Physics: Definition and Examples

Distance and displacement might seem like similar terms but in physics, understanding the difference can mean getting a question right instead of wrong. In this lesson, we will define these terms and illustrate how easy it is to confuse the two.

Speed and Velocity: Difference and Examples

3. Speed and Velocity: Difference and Examples

Is it possible to drive with a speed of 100 mph but a velocity of 0? In this lesson, we will examine the difference between speed and velocity and use that information to answer this question.

What is Acceleration? - Definition and Formula

4. What is Acceleration? - Definition and Formula

This lesson describes the difference between speed, velocity and acceleration. Examples are used to help you understand the concept of acceleration and learn to calculate acceleration with a mathematical formula.

Determining the Acceleration of an Object

5. Determining the Acceleration of an Object

Acceleration is a change in an object's state of motion. A few variables need to be identified to calculate an object's acceleration, but once we have those values, we can put them into a simple equation to find out how quickly or slowly an object's velocity is changing.

Velocity vs. Time: Determining Displacement of an Object

6. Velocity vs. Time: Determining Displacement of an Object

There is a lot of information you can determine by looking at a velocity vs. time graph. In this lesson, we will use a little geometry to calculate the displacement of the object represented by the graph.

The Acceleration of Gravity: Definition & Formula

7. 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.

Uniformly-Accelerated Motion and the Big Five Kinematics Equations

8. Uniformly-Accelerated Motion and the Big Five Kinematics Equations

In this lesson, we will begin to solve problems that combine position, displacement, velocity, and acceleration. I will introduce the Big Five Equations to help you on your way.

Air Resistance and Free Fall

9. 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.

Free Fall Physics Practice Problems

10. Free Fall Physics Practice Problems

In this lesson, we will dive into doing calculations involving free falling objects. We will begin with a few helpful tips to get started before working through a couple of example problems.
