We explore static electricity as we learn about charging by friction, conduction, and induction.
Unit 5 Segment B: Static Electricity: Conduction and Induction We explore static electricity as we learn about charging by friction, conduction and induction.Premiere Date: August 2, 2018 | Runtime: 00:09:13
-Define static electricity.
-Discuss properties of conductors and insulators.
-Explain charging by conduction, friction, and induction.
-Explain what it means if an object is electrically polarized.
-Investigate the law of conservation of charge.
conduction - the transfer of charge by direct contact.
conductor - a material across which electrons can easily travel.
charging by friction - the transfer of electrons by two objects being rubbed together.
electrostatic force (FE) - one of the four fundamental forces of the universe; the attraction and repulsion of particles based on their electrical charges; is equal to Coulomb’s constant times the magnitude of two charges divided by the distance between the charges, squared.
induction - charging a neutral object by bringing a charged object close to but not touching the object.
insulator - material that resists the movement of charge.
law of conservation of charge - electric charge cannot be created or destroyed but can be transferred from one object to another.
static electricity - the accumulation of electric charge on the surface of or within a material.
triboelectric series - a list of materials that ranks materials by how easily they give up or receive electrons.
polarization - the process of separating opposite charges within an object.
The Physics in Motion teacher toolkit provides instructions and answer keys for study questions, practice problems, labs for all seven units of study. GPB offers the teacher toolkit at no cost to Georgia educators. It will be available in September 2018. To preorder your teacher toolkit, complete and submit this form to request the teacher toolkit. You only need to submit this form one time to get materials for all seven units of study.
