Static electricity is what makes: clothes stick together when they come out of a dryer gives you a shock with you touch a metal doorknob.
Electric charges allow an object to exert an electric force on another object without touching it. The space around a particle where an electric charge can exert this force is called an electric field. The strength of the field is greater near the particle and weaker farther away.
All protons have a positive charge (+), and all electrons have a negative charge (-). usually, atoms have an equal number of protons and electrons, so their charges balance each other, and the charge of the atom is neutral.
Particles with the same type of charge (positive or negative ) have like charges, and particles with different charges have unlike charges. Particles with like charges repel each other (push away)
Particles with unlike charges attract each other, or pull toward each other.
A static charge is a buildup of electric charge caused by particles with the same charge. A material develops a static charge when it contains more of one type of charged particles than another.
Electrons can move from one atom to another. The movement of electrons through a material is called conduction.
If electrons move from one atom to another. The atom they move to develops a negative charge. The atom they move away from develops a positive charge.
Magnet’s work the same way: Like charges repel each other Unlike charges attract one another Materials are magnetic based on how their atoms are arranged
1. Like Charges? 2. Unlike Charges? 3. Static Electricity is caused by the movement of: 4. Charge of Protons: 5. Charge of Electrons: 6. Charge of Neutrons: 7. Movement of electrons by physically touching something: 8. The charge around a magnet: 9. Magnets are stronger: (closer together, far away) 10. Can magnets become demagnetized?
