- Section 2-1
- Slide 2
- Objectives N.2.1.1. Explain how electric charges interact. N.2.1.2. Explain what an electric field is. N.2.1.3. Describe how static electricity builds up and transfers.
- Slide 3
- Electric Charge Charges that are the same repel each other and charges that are different attract each other. N.2.1.1. Sound familiar? Magnetic poles follow the same rules.
- Slide 4
- Electric Force Electric Force is the attraction of repulsion between electrically charges particles. An electric field is the region around a charges particle where electric force is exerted on other charged particles. Objective N.2.1.2. Sound familiar? Just like magnetic fields!!!
- Slide 5
- Electric Fields Around Single Charges The electric field from a positive charge point outward while the electric field from a negative charge points inward.
- Slide 6
- Electric Fields Around Multiple Charges When two charges are brought close to each other, their electric fields are combined.
- Slide 7
- Combined Electric Fields OppositeLikes
- Slide 8
- Combined Electric Fields: Cool Picture
- Slide 9
- Static Electricity Static means not moving so, in static electricity charges build up on an object but they do not flow. Objective N.2.1.3.
- Slide 10
- Transferring Charge There are three methods for transferring charge from on object to another: Friction Conduction Induction
- Slide 11
- Friction Friction is the transfer of electrons by rubbing objects together.
- Slide 12
- Conduction Conduction is the transfer of electrons by two objects touching. Sound familiar? Heat can also be transferred by conduction.
- Slide 13
- Induction When a charged object is brought close to another object, the charges separate by induction. The objects dont need to touch.
- Slide 14
- Static Discharge When a negatively charged object and a positively charged object are brought close together, electrons may transfer until both objects have the same charge again. Objective N.2.1.3.
- Slide 15
- Lightning
- Slide 16
- Lightning is the most dramatic natural form of static discharge. Trillions upon trillions of electrons suddenly jump from the cloud base to the ground.
