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
Located in GC
Turn it in.
Watch the “Cheat Codes - Balloons and Static Charge vs Speed Graphing How-to Video” to help
Students who were absent will be accommodated.
Rocket Launch Update
Monday
Preflight checks - passed in/entered.
Launch order - random
Transcribe the following Class Notes into your notebook.
Atomic Structure
nucleus
protons (positive charge)
Neutrons (neutral charge)
Electron Cloud
Electrons, orbit nucleus, negative charge
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
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.
Electric Forces
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.
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
