Ch 28: TASC Science: Types of Interactions

About This Chapter

In preparation for the TASC Science exam, complete the activities in this chapter to fortify your understanding of the forces in physics that affect interactions between objects. Each lesson includes a quiz that allows you to assess your understanding of key points.

TASC Science: Types of Interactions - Chapter Summary

Begin this chapter by watching videos of our professional instructors explaining the forces that interact between objects, including gravitational, electric and magnetic forces. If you develop a question during the course of this chapter, be sure to send it to our instructors for clarification so that they can assist you in your mastery of this material. At the end of the chapter, you should be prepared for questions on the Test Assessing Secondary Completion (TASC) Science test asking about:

  • Newton's Law of Gravitation
  • Coulomb's Law and the force between two charged particles
  • Attractive and repulsive forces of electric charges
  • Electric force fields
  • Magnetic fields
  • Moving charges and magnetic forces
  • Macroscopic properties of matter and microscopic forces

After watching these lesson videos, you can complete lesson worksheets and quizzes to insure your retention of the information presented in this chapter. You can then use your quiz results to find areas of weakness and return to where these areas were discussed in the lessons to fortify your understanding. For an alternative review of the chapter, read over the lesson transcripts that give an written overview of the videos.

TASC Science: Types of Interactions Objectives

TASC Science is a subtest of the TASC high school equivalency exam. The TASC Science exam is administered in both a computerized and paper format and in two languages. The English version of this exam is given in an 85-minute testing session and the Spanish version in a 90-minute session.

These tests include 48 multiple-choice (49 for the paper-based exam), one constructed-response and one technology-enhanced (for the computer-based exam) questions. Of the material covered in this exam, 36% of the questions fall under the domain of Physical Sciences (with at least two to five questions about forces and interactions). Watching the lesson videos and completing the lesson worksheets and quizzes in this chapter will aid your review of these interactions so that you can be prepared for these questions on test day.

9 Lessons in Chapter 28: TASC Science: Types of Interactions
Newton's Law of Gravitation: Definition & Examples

1. Newton's Law of Gravitation: Definition & Examples

This lesson explains how gravity works mathematically and teaches you how to use Newton's Law of Gravitation to solve problems. A short quiz will follow.

Coulomb's Law: Variables Affecting the Force Between Two Charged Particles

2. Coulomb's Law: Variables Affecting the Force Between Two Charged Particles

In the 18th century, Charles Coulomb uncovered the secrets of electrostatic force between charged particles. The results of his experiments led to what is now known as Coulomb's Law, which tells us how force, charge, and distance are all related.

Electric Charge and Force: Definition, Repulsion & Attraction

3. Electric Charge and Force: Definition, Repulsion & Attraction

Have you ever wondered what electricity is and where it comes from? Have you ever been zapped by static electricity and wondered how it got there? We'll answer all of these questions in this lesson on electric charge and force!

Electric Force Fields and the Significance of Arrow Direction & Spacing

4. Electric Force Fields and the Significance of Arrow Direction & Spacing

Did you know that force fields don't just exist in science fiction movies? In this lesson, we'll explore the electric force fields that surround charged particles and how we can draw diagrams that represent them.

Magnetic Force: Definition, Poles & Dipoles

5. Magnetic Force: Definition, Poles & Dipoles

You're probably familiar with magnets, but have you ever stopped to consider how they work? In this lesson, we'll look at the root of magnetism and some of the fundamental properties of magnets.

What is a Magnetic Field?

6. What is a Magnetic Field?

Magnetic fields fill the space around all magnets, but they're impossible to detect with our own senses. We'll use a common tool to map out a magnetic field and then discuss ferromagnetic materials to see how a magnetic field can be used to create new magnets.

How Magnetic Fields Are Created

7. How Magnetic Fields Are Created

Have you ever wondered how magnetic fields are created? In this lesson, we'll discuss the very simple answer to this question and look at how electric current can be used to make electromagnets, which have many everyday applications.

How Magnetic Forces Affect Moving Charges

8. How Magnetic Forces Affect Moving Charges

A magnetic field exerts a force on a moving charged particle in ways that you might not expect. In this lesson, we're going to look at the direction of this force and the factors that affect its strength.

The Effects of Microscopic Forces on Macroscopic Properties

9. The Effects of Microscopic Forces on Macroscopic Properties

Microscopic forces between atoms explain why contact forces exist between solid objects and why materials can change states of matter. Covalent, ionic and hydrogen bonds also have effects on macroscopic properties. Read on about forces and bonds.
