Charges

• Postive + Negative = Attraction
• Negative + Negative = repulsion
• Postive + Positive = Repulsion
• No charges + Neutral
• Matter – made up of atoms.
• ATOM - the basic unit of a chemical element.
• Objects charge by losing an electrons.
• When rubbing something losses electrons. It gets charge.
• Only electrons losses because they are located outside the nucleus.
• Loses electrons something becomes POSITIVELY CHARGED.
• Don’t gain/Don’t lose -Neutral charged.
• Gain electrons the object - Negatively charged.
• Law of Charges - Opposite charges attract and like charges repel.
• When something gets loses electrons it gets postively charged
• When something gains electrons it gets negatively charged
• when rubbing something losses electrons, it gets postively charged
• Charging by Friction – occurs when rubbing two different materials.
• Charging by Conduction – when electrons are transferred from one material to another by direct contact.
• Charging by Induction – A charging process where an object can charged without actual contact with any other charged object.
• ELECTRICITY - also known as electrical energy.
• When a negative touches a negative material it causes repulsion
• When a negative keyboard touches a postive mouse it is attraction
