Electric charge
Electric charge
Fundamental property of matter in all objects
Electrostatics
Electrostatics
Study of electric charges at rest (not moving)
Two types of electric charge
Two types of electric charge
Positive (protons) and negative (electrons)
Electrically neutral object
Electrically neutral object
Equal amounts of positive and negative charges
Particles that move during charging
Particles that move during charging
Only electrons; protons stay fixed in nucleus
How object becomes positively charged
How object becomes positively charged
Electrons removed (electron deficient)
How object becomes negatively charged
How object becomes negatively charged
Electrons added (excess of electrons)

Tribo-electric charging
Charging by contact or rubbing materials together
Like charges behaviour
Like charges behaviour
