Coulomb's law

Physics course theme- Coulomb's law often mean nothing to us and we cannot imagine where we can see it in nature and in our daily lives. To familiarize yourself with this topic, and learn the basics, you need to understand and learn the foundations of the theory of how this law operates and where we can see it. In the video, when parallel is both substance and drawing examples, it is easier and better to learn about various topics, so in this topic we will explore video material assistance. I hope that everything goes well, video is not too long, but it covers important information that will be rquired after watching this video! 

Watch the video about Coulomb's law and then answer the questions!

Answer to these questions:

1. What is Coulomb's law?

2. How represents first charge and second charge size?

3. Equal mark charges attracts or repels?

4. On what strenght does projectile interaction depend on?

5. With increasing distance power rapidly increase or decrease?

6. How changes force, if positive charges pushes fast away from one another?

7. What is the Gravity force formula?

8. In which measure unit, measured charges?

9. How large a single electron possess pendant charge?

10. How to denote power and how it is measured?

Question answers:

1.Interaction forces between the fixed charges is directly proportional to the charge modules and inversely proportional to the square of the distance between them;

2. and ;

3. Repels;

4. From a distance;

5. Decrease;

6. If the positive charge is pushed away from each other, mutual strength will be lower;

7. 

8. C (coulombs)

9. l= 1,6*10-19C

10. F, measured in N (Newtons)

Congratilations! It is now mastered the theme of Coulomb's law! You're mastered the basics of Coulomb's law and understood the theory!

This material has helped you to see what charges interaction works, what are the gravitational and Coulomb's Law formulas and how to be identified and measured values to important formulas.

For a better understanding of this and other themes, it is advisable to look throught E. Šiltera, V. Reguta, A. Cābeļa and I. Vilka physics book for class 11,as well as various internet sites such as uzdevumi.lv.

Information and video was taken from www.youtube.com, Riga Secondary School No. 1 video material. This material has been authorized and even recommended to use the classroom to complement the students' knowledge and awareness, as well as independent thinking. It shows that physics can be fun by drawing various examples, so you can easier understand the theory.
