About This Chapter
ILTS Environmental Science: Forces and Motion - Chapter Summary
This chapter's lessons cover the concepts and interrelationships of motion, including velocity and acceleration, as well as force, which involves inertia, work and momentum. You can explore Newton's Laws of Motion and discover the instruments and technologies that are used to study force and motion. The video lessons include the following topics that can help you with these types of questions on the ILTS Environmental Science exam:
- Acceleration - definition and formula
- The relationship between two forces
- Concepts and formulas regarding speed and velocity
- The relationship between force and acceleration
- The effect of force on motion
- Newton's Laws and weight, mass and gravity
Each video lesson is taught by an expert instructor in the field. By the end of this chapter, you will have been exposed to the information you need to correctly answer the test questions on forces and motion.
Objectives of the ILTS Environmental Science: Forces and Motion Course
Individuals who want to teach environmental science at the secondary level in Illinois must pass the Illinois Licensure Testing System (ILTS) content area exam in that subject. The exam contains 125 multiple-choice questions that are divided among six subareas. The topics from the chapter on forces and motion are included in subarea III, which covers physical science. You can become familiar with the format of the test by completing the self-assessment quizzes that follow each lesson.
1. 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.
2. 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.
3. Implications of Mechanics on Objects
Forces act on objects causing them to move. Mechanics is the field of science designated to the study of moving objects. This lesson describes how forces act on objects resulting in motion. Examples are used to describe how forces interact resulting in both simple and complex movement.
4. Speed and Velocity: Concepts and Formulas
Did you know that an object's speed and velocity may not be the same? This lesson describes the concepts of speed and velocity relating to objects in motion. We'll look at a specific example to help learn how to calculate both speed and velocity.
5. 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.
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.
7. 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.
