Video 1: Explores what angles are
Video 2: Provides examples of angles
Video 3: Misconceptions about angles

This video explores the angles found in parallel lines.

These three short online lessons discuss asteroids, comets and meteors.

• Determine the variables that affect how charged bodies interact.
• Predict how charged bodies will interact.
• Describe the strength and direction of the electric field around a charged body.
• Use free-body diagrams and vector addition to help explain the interactions.

In this course you will learn about:

1. Angles and lines
2. Angles formed between parallel lines.
3. Classifying polygons.
4. Quadrilaterals.

Other objects in the solar system are discussed in this online textbook viz. asteroids, meteorites, comets and dwarf planets.

Electric charge comes in two varieties, which we call positive and negative. Like charges repel each other, and unlike charges attract each other. Thus, two positive charges repel each other, as do two negative charges. A positive charge and a negative charge attract each other.

How do we know there are two types of electric charge? When various materials are rubbed together in controlled ways, certain combinations of materials always result in a net charge of one type on one material and a net charge of the opposite type on the other material. By convention, we call one type of charge positive and the other type negative.

This video explores the different types of angles that exist.
