U2L2 electric forces

What are the 3 charges of electric force?

positive, negative, neutral

Charged objects have

an electric field surrounding them

The strength of attraction or repulsion depends on

the size of the charge or the distance between the two objects

Like charges

repel

opposite charges

attract

when charged objects get farther apart

the force decreases

All matter has atoms with —, —, and —

protons, neutrons, electrons

protons and neutrons are held

electrons are held

inside the nucleus

spinning outside the nucleus

because protons and neutrons are inside the nucleus it has a

positive charge

why are electrons attracted to the nucleus

because the nucleus has a positive charge, and the electrons are negative. opposites attract

atoms are usually neutral because

the number of electrons is equal to the number of protons

if two neutral materials are rubbed together, friction causes — to move and not —.

electrons, protons

if an object gains electrons it is

negatively charged

if an object loses electrons it is

positively charged

What is induction?

Induction is the process by which an electrically charged object can cause a neutral object to become charged without direct contact. This happens when an electric field from the charged object induces the movement of electrons in the neutral object, resulting in one side becoming positively charged and the other side negatively charged.

what is the law of conservation of charge?

charges are not created nor destroyed. they are transferred

protons have

positive charge

electrons have

negative charge

neutrons have

neutral charge

natural materials

lose electrons and become positively charged

synthetic materials

gain electrons and become negatively charged
