Ch 1: Georgia Milestones - Physical Science EOC: Motion & Force

About This Chapter

Watch brief video lessons to learn about the nature of force and the laws of motion for the Georgia Milestones - Physical Science EOC assessment. Lessons come with handy quizzes to ensure you are ready for test day.

Georgia Milestones - Physical Science EOC: Motion & Force - Chapter Summary

In this chapter, our instructors will teach you about the definition of motion, the definition of force, balanced and unbalanced forces, and the calculation of variable forces. The lessons here have relevance to the portion of the Georgia Milestones - Physical Science EOC assessment that tests you on your knowledge of energy, force, and motion. There are also lessons here about the determination of individual forces acting on an object and the distinction between inertia and mass. Other topics covered in the chapter include:

  • Acceleration: definition and formula
  • Motion, speed, and velocity
  • Speed, position, and time
  • Friction: definition, formula, and forces
  • Newton's three laws of motion
  • Weight, mass, and gravity

The structure of our lessons enables the instructors to teach you the information you need to know with a minimum of fuss. Each informative video is topic-searchable so that, when you review, you can save time by skipping to the part you need. Lesson transcripts help you cover the same material in a different way, which helps boost comprehension and retention. You can self-test with the quizzes and chapter exam, and the instructors are available to answer your questions.

What is Motion? - Definition & Laws

1. What is Motion? - Definition & Laws

Motion is the act of moving and plays a huge role in the study of physics. This lesson walks through important terms and the laws of motion that guide the study of motion.

Force: Definition and Types

2. 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.

Forces: Balanced and Unbalanced

3. Forces: Balanced and Unbalanced

Forces are needed to start or stop an object's motion, but can also be involved when an object is at rest or already traveling at constant velocity. In this video lesson, you'll identify the difference between balanced and unbalanced forces, understanding how they affect the movement of objects.

Work Done by a Variable Force

4. Work Done by a Variable Force

Doing work on an object is a simple concept: we apply a certain force over a certain distance. But in real life, that force is rarely constant. Therefore, we need to understand variable forces and be able to calculate them accurately.

Determining the Individual Forces Acting Upon an Object

5. Determining the Individual Forces Acting Upon an Object

Objects constantly have forces acting on them whether they are moving or at rest. In this video lesson, you'll understand how to identify the individual forces acting on an object by reviewing the different types of forces and the use of free-body diagrams.

Distinguishing Between Inertia and Mass

6. Distinguishing Between Inertia and Mass

Mass and inertia are both related to the amount of matter an object has, but they aren't exactly the same thing. In this video lesson, you'll see how mass affects an object's inertia, which in turn affects that object's motion.

What is Acceleration? - Definition and Formula

7. 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.

State of Motion and Velocity

8. 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.

Graphing Position & Speed vs Time: Practice Problems

9. 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.

What is Friction? - Definition, Formula & Forces

10. What is Friction? - Definition, Formula & Forces

Friction is the force that opposes the motion of an object. Learn about the sources of friction, identify examples of friction and test your knowledge with quiz questions.

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

11. 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

12. 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

13. 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.

Newton's Laws and Weight, Mass & Gravity

14. Newton's Laws and Weight, Mass & Gravity

Did you know that mass and weight are not the same? This lesson describes the difference between the two as well as the effect of gravity on weight. Examples are used to teach you how to calculate weight based on mass and acceleration of gravity.
