Forces: contact and non-contact
Newton’s laws and contact forces
Can you think of forces that don’t touch?
Phenomenon: Junkyard Show
What do we call a form of energy that results from the flow of electric charge?
Electric Charge: Physical property that allows objects to attract or repel without touching. It is based on the number of protons and electrons in an atom.
Opposite charges attract each other
Like charges repel each other
Electric field: area around a charged particle where electric force is exerted
Static Electricity
- When atoms gain or lose electrons, they become a charged particle called an ion.
- If objects are close enough together, they will exert a force on each other when their electric charges interact.
How could we explain these phenomena?
Repel
Attract

Where do magnets go to play baseball?
Magnets
Magnets
The poles align with Earth’s north and south pole! All magnets have a north and south pole Magnets are strongest at their poles.
If you cut a magnet in half, you get two magnets (each half would have north and south poles)
Magnetic Domains
MAGNETIC metals like iron, nickel and cobalt have domains oriented north and south.
NON-MAGNETIC metals like silver and lead will have randomly oriented domains.
Opposite poles attract Like poles repel
Will these two magnets attract or repel each other?
ATTRACT!
Will these two magnets attract or repel each other?
REPEL
Opposite forces attract
Similar forces repel
