✓ MOST learners will be able to give examples of positive and negative
effects of charging
✓ SOME learners will be able to explain charging by rubbing, induction and
contact.
Subject Learning:
Learners can characterize electric charge
Language Learning:
✓ Learners can interpret sketch graphs to explain force between charges
(speaking and listening skills OR reading and writing skills)
SubjectSpecific Vocabulary and Terminology:
neutral atom, electron, positive ion , electrical charges, positive charge, negative
charge
(бейтарап атом, электрон, оң ион, электр заряды, оң заряд, теріс заряд,)
• Positive charge every proton has a single positive charge.
• Negative charge every electron has a single negative charge
• The charges can attract [pull] and repel [push] each other.

• Electrostatics is the study of electric charge at rest.
• Electric charge is a fundamental property of matter.
• Two types of electric charges
• Positive charge every proton has a single positive charge.
• Negative charge every electron has a single negative charge.
Note that the electron and proton both have the same charge, with
the electron being negative and the proton being positive. This amount
of charge is often called the
electronic charge, e. This electronic charge is generally considered a
positive value (just like g in gravity). We add the negative sign when
we need to:
qe = e; qp = +e.

The charges can attract [pull] and repel [push] each other. Like [same]
charges repel each other. Unlike [not same] charges attract each other.
Two different kinds of charge, positive and negative
.
Electricity, with attractive and repulsive forces, needs two kinds of
charge.
• Electric charge is measured in coulombs (C)
Properties of electric charge
1.Two kinds of charges occur in nature,
like charges repel one another,
and unlike charges attract one another.

2. Charge is conserved.
3. Charge is quantized.
• An object becomes electrostatically charged by:
1. Friction,which transfers electrons between two objects in contact,
1. Contact with a charged body which results in the transfer of
electrons,
2. Induction which produces a charge redistribution of electrons in a
material.
III. Home task: Give examples of positive and negative effects of
charging
