What is Static Electricity?

Where does static charge come from? electron (negative charge) Around the outside of an atom are electrons, which have a negative charge. The nucleus at the centre of an atom contains protons which have a positive charge. proton (positive charge) An atom has equal amounts of negative and positive charges which cancel each other out. This means an atom has no overall charge. Electrons do not always stay attached to atoms and can sometimes be removed by rubbing. In the air in your classroom there are about 1500000000000000000000000000 atoms.

What is Static Electricity? Electric Charge: an uneven buildup of electrons. .

What is Static Electricity? How to make an electric charge? -electrons can be added or removed from atoms fairly easily

What is Static Electricity? How to make an electric charge? -electrons can be added or removed from atoms fairly easily Remove electrons: substance becomes positive

What is Static Electricity? Electric Charge: a negative or positive charge that exerts an electric force. How to make an electric charge? -electrons can be added or removed from atoms fairly easily Remove electrons: substance becomes positive Add electrons: substance becomes negative

What is Static Electricity? We don't draw atoms, just "+" and "–" to illustrate the overall charges

Here’s my silly demo. The balloon will rub against the head and then pull away with the “hair” standing on end. You might need to explain what it’s supposed to be. The next few slides show what is happening to the charges. These should run automatically.

The balloon is now negatively charged and the head positively charged so that because opposites attract the hairs are attracted to the balloon And because like charges repel the airs are pushed apart from each other. +

What is Static Electricity? We don't draw atoms, just "+" and "–" to illustrate the overall charges e.g. a neutral object 5 + 5 - overall charge 0

What is Static Electricity? We don't draw atoms, just "+" and "–" to illustrate the overall charges e.g. a positive object 5 + 3 - overall charge 2+

What is Static Electricity? We don't draw atoms, just "+" and "–" to illustrate the overall charges e.g. a negative object 5 + 8 - overall charge 3 -

What is Static Electricity? Static Electricity: an imbalance of electric charge on the surface of an object; stationary electric charge John Travoltage in action

What is Static Electricity? Law of Electric Charges:

What is Static Electricity? Law of Electric Charges: 1. Opposite charges attract

What is Static Electricity? Law of Electric Charges: 1. Opposite charges attract 2. Like charges repel

What is Static Electricity? Law of Electric Charges: 1. Opposite charges attract 2. Like charges repel 3. Charged objects attract neutral objects

How does our atmosphere buildup unbalanced electric charge?

Interesting facts Lightning bolts can travel at speeds of up to 60,000 miles per second. Every second around 100 bolts of lightning strike the Earth. One lightning bolt has enough electricity to power 200,000 homes. You are more likely to be struck by lightning than be eaten by a shark.
