Ch 4: STAAR Science - Grade 8: Force & Motion

About This Chapter

As your student(s) prepare for the STAAR Science - Grade 8 exam, have them complete these lessons to review the laws of motion, the different types of force, the parameters of motions and inertia, calculations for motion and how to graph values of motion.

STAAR Science - Grade 8: Force & Motion - Chapter Summary

To help your student(s) improve their understanding of force, inertia and motion have them work through these short and engaging lessons. After these lessons, your student(s) should be better prepared to answer questions on the STAAR Science - Grade 8 exam regarding:

  • The definition and types of force
  • Newton's laws of motion
  • Unbalanced force and how it can cause motion
  • Calculations for force and motion
  • Definitions and differences between speed, velocity and acceleration
  • Calculations for average speed and distance
  • Graphs that represent the motion, position and speed of an object

Your student(s) can further improve their understanding of force and motion by reading the lesson transcripts. They can also test their understanding of the lessons and identify topics they don't understand by taking the lesson quizzes. If you or your student(s) comes up with questions regarding lesson topics, use the teacher tabs of the lessons to ask our professional instructors for clarification.

10 Lessons in Chapter 4: STAAR Science - Grade 8: Force & Motion
Test your knowledge with a 30-question chapter practice test
Force: Definition and Types

1. Force: Definition and Types

Force is everywhere and it comes in a variety of sizes, directions, and types. In this video lesson, you'll identify force as well the different types of force that objects may experience.

Action and Reaction Forces: Law & Examples

2. Action and Reaction Forces: Law & Examples

Action force is force acting in one direction. Reaction force is force acting in the opposite direction. Learn more about Newton's Third Law as it explains action and reaction forces through several examples, and test your knowledge with quiz questions.

Unbalanced Force: Definition & Example

3. Unbalanced Force: Definition & Example

Unbalanced forces are forces that cause a change in the motion of an object. Learn more about how to identify balanced and unbalanced forces through several examples and test your knowledge with quiz questions.

What Is Motion? - Definition & Equations

4. 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.

Speed, Velocity & Acceleration

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.

Laws of Inertia: Definition & Formula

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.

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

7. 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.

Distance, Time & Average Speed: Practice Problems

8. Distance, Time & Average Speed: Practice Problems

After watching this video, you will be able to explain what distance is, explain how it relates to change in position, and calculate the average speed in various situations. A short quiz will follow.

Graphing the Motion of Objects: Physics Lab

9. Graphing the Motion of Objects: Physics Lab

After watching this lesson, you will be able to measure the motion of an object and plot position-time and velocity-time graphs based on your data. A short quiz will follow.

Graphing Position & Speed vs Time: Practice Problems

10. Graphing Position & Speed vs Time: Practice Problems

After watching this video, you should be able to explain what position and speed are. You should also be able to plot position vs. time and speed vs. time graphs. A short quiz will follow.
