Static electricity

QuestionAnswer
Define electricity Form of energy created from the movement of electrons
Define static electricity Buildup of non-moving electric charges on a surface. Ex. balloon rubbed on hair sticks because charged are transferred and opposite charges are given.
Law of static electric charges (attract/repel) Opposite charges attract. Neutral and charged attract. Same charges repel.
Friction Charging an object by rubbing 2 materials together (1 object loses electrons, other gains and becomes negative)
Contact Non-charged object charged by touching a charged object. How: charged materials releases electrons to another (shock)
Induction Bring a charged object CLOSE to an uncharged one; causes a temporary change. Ex. pithball and ruler trick.
Insulator vs conductor (define) Insulator is a materials that does not allow easy flow of electrons through it, such as rubber. Conductors allows the flow of electrons through it, such as metal: some materials are better conductors than others.
Static electricity is detected by… Pith-ball electroscope and gold leaf electroscope
Define discharge Getting rid of excess electrons. Ex. Holding pithball with hand.
Define grounding Discharging electrons to the ground ex. Lightning rod, 3rd cord prong.
Lightning safety precautions: Go indoors, don’t lay down (current will be grounded on your path), stay low, keep feet together to avoid giving electrons a shortcut to transfer through, or have metal armour (faraday cage).
What is a Faraday cage? A conductive enclosure that blocks electromagnetic charges from penetrating through, instead making it glide over.

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.
