Thursday, December 15, 2022. Day 4

Do Now:

Homework to be completed:

finish ELECTRIC CHARGE AND FORCES LESSON 1 OUTLINE.

  • for tomorrow.

Make sure any and all work assigned during mys absence Monday-Wednesday is compelted and turned in.

Todays agenda:

Late Work Notices sent

Finish all work on Balloons and Static Charge vs Speed Graphing

Rocket Launch Update

  • Monday

  • Preflight checks - passed in/entered.

  • Launch order - random

Transcribe the following Class Notes into your notebook.

  1. Atomic Structure

    • nucleus

      • protons (positive charge)

      • Neutrons (neutral charge)

    • Electron Cloud

      • Electrons, orbit nucleus, negative charge

  2. electrons are “easily” lost/gained by atoms

    • Atoms are normally “neutral” meaning they have equal numbers of positive and negative particles that balance.

    • When an atom loses electrons, it becomes positively charged.

    • atoms that gain electrons become negative

  3. Charged objects

    • objects are also normally neutral.

    • when the atoms that make them up gain or lose electrons they becoem charged

    • extra electrons - negative

    • fewer electrons - positive

    • Static charge - unbalanced negative or positive charge on an object.

  4. Electric Forces

  5. Charged objects are surrounded by an electric field

    • Electric Field - regions influenced by electric forces

    • other charged objects are attracted or repeled in this field

    • opposite charges (+,-) attract

    • Similar charged (-,- or +,+) repel.

  6. Charge and Distance affect field strength

    • The more charge an object has the stronger the field

    • Stronger forces occurs close and weaker ones further away

finish ELECTRIC CHARGE AND FORCES LESSON 1 OUTLINE.
