Physical Science

Two things rubbing together is an example of…

• an object at rest

• zero gravity

• magnetic force

• friction

Magnetism is a non-contact force were the magnets do not need to touch an object for that object to start moving. Which ends of the magnets will repel each other through a magnetic push force?

• north end & north end

• north end & south end

• magnet & iron nail

• electrons & protons
