### About This Chapter

## TExES Physics/Math 7-12: Motion - Chapter Summary

As part of a preparation course for the Texas Examination of Educators Standards (TExES) Physics/Mathematics 7-12, these lesson videos cover the nature of motion, the forces that affect it and the mathematical representations of it. Watch as our expert instructors prepare you for questions on:

- Newton's three laws of motion
- Effects of air resistance
- Calculations for velocity, speed and acceleration
- Graphical representation of motion
- Working with inclined planes
- Torque and circular motion
- Forces that can initiate and reduce motion

Take as much or as little time as you like to complete these entertaining lessons. They're designed to be self-paced and convenient. In fact, you can study the laws of motion even when you're on the go when you utilize a Web-ready mobile device such as a tablet or laptop.

### TExES Physics/Math 7-12: Motion Objectives

The TExES Physics/Mathematics 7-12 certification exam is used to certify math and physics teachers in the state of Texas. It is a computer-based exam consisting of 120 multiple-choice questions, 39% of which are about physics and may include questions on motion or kinematics. These lesson videos, worksheets and quizzes have been assembled to help you determine what you know about motion.

### 1. 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.

### 2. 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.

### 3. 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.

### 4. Air Resistance & Free Fall Physics: Practice Problems

Learn what we mean by free fall, and how air resistance affects objects falling through the air. Then we'll work though a couple practice problems to see how objects act while they are in free fall.

### 5. Speed, Velocity & Acceleration

Speed and velocity are not the same thing. Objects' speed and velocity can be identical or very different, depending on their directions of motion. In this article, learn more about these foundational physics concepts, including acceleration and free-falling objects.

### 6. Overview of Graphs of Free Fall Motion

After completing this lesson, you will be able to explain what free fall motion is, and identify and draw displacement, velocity, and acceleration-time graphs for free fall motion.

### 7. Inclined Planes in Physics: Definition, Facts, and Examples

If an object is not horizontal to the ground, it may be on an inclined plane. We need to adjust both the calculations and the free-body diagram when determining the net force on an object on an inclined plane. Learn how in this lesson.

### 8. Torque in Physics: Equation, Examples & Problems

After watching this video, you will be able to explain what torque is and use an equation to calculate torque in simple situations. A short quiz will follow.

### 9. Static Equilibrium of Rigid Bodies

What is static equilibrium? Learn about the factors that cause an object to remain stationary, without translating or rotating. Then take a quiz to make sure your understanding hasn't remained static.

### 10. Overview of Force & Free-Body Diagrams

After completing this lesson, you will be able to explain what a free-body force diagram is, some of the rules associated with them, and what needs to be considered when drawing these diagrams.

### 11. Uniform Circular Motion: Definition & Mathematics

After watching this lesson, you will be able to explain what uniform circular motion is, in terms of both acceleration and forces. You will also be able to use equations for centripetal force and acceleration to solve problems. A short quiz will follow.
