Magnetism
These are considered the two poles of a magnet.
North & South
Fill in the blank: ________ allows materials to pass through and flow easily. Examples include copper, aluminum, iron, etc.)
Conductor(s).
This is the force that pulls objects toward each other.
Gravity.
Opposite magnetic poles do this when near each other.
They attract.
This particle carries a negative charge.
Electron.
What happens when two "like" poles of a magnet are brought together or in close proximity?
They repel each other.
Fill in the blank: ________ is the flow of electric charges, and usually carried by electrons through conductors such as wire.
Electricity.
Fill in the blank: The farther apart objects are, the ___ the gravity.
This factor increases gravity when the amount of matter in an object increases.
Mass.
This type of materials that do NOT allow electricity to flow through easily.
Insulator(s).
This is a phenomenon produced by motion of electric charges which results in attractive and repulsive forces between objects.
Magnetism.
What unit(s) are electricity and electric currents measured in?
This keeps planets moving around the Sun.
Gravitational Force.
This is a buildup of electric charges on an object.
Static Electricity.
The unit used to measure force.
Newtons. (N)
This is the region around a magnet where magnetic forces act.
Magnetic Field.
This type of magnet is created by electricity.
Electromagnet.
This scientist explained gravity with laws of motion.
Sir Isaac Newton.
This is measured in kilograms (kg) and does not change; stays constant.
Mass.
Fill in the blank: ________ is a force that resists motion between two surfaces that are touching.
Friction.
This planet acts like a GIANT magnet.
Earth.
This device or object provides energy in a circuit.
(Hint: referred to as a type of energy used in digestion)
Fill in the blank: Force of gravity on an object is called ______.
Weight.
A device that uses Earth’s magnetism to find direction.
a compass.
This is a type of battery that produces electricity using chemicals inside a sealed container with little or no liquid. AA and AAA batteries used in remotes, flashlights, and toys.
