Gravity
A force that attracts objects toward each other based on their masses. It keeps planets in orbit around stars and governs the motion of objects in space.
Distance
The amount of space between two objects - typically measured in units like kilometers (km), miles, or astronomical units (AU) when referring to extremely long distances in space.
Mass
The amount of matter in an object, which determines its gravitational pull. Larger mass = greater gravitational force.
Orbit
The curved path an object takes when moving around a planet or star.
Pull
A force that moves an object toward the source of the force.
System
A set of interacting parts that work together to form a complex whole.
Potential Energy
The energy that is stored in an object or system.
Kinetic Energy
The energy that an object has because it is moving
Energy
The ability to make things move or cause change.
Variable
Something that can be changed and may be measured.
Transfer
To move from one object to another or one place to another.
Convert
To change from one type to another type
Isolate
To separate or set apart
Refute
To provide evidence that goes against the claim or answer
Electromagnet
A type of magnet in which the magnetic field is produced by an electric current.
Attract
To pull objects towards one another
Repel
To push objects away from each other
Magnetic Field
The area around a magnet in which the magnetic forces can act on objects.
Magnetic Field Line
A line that connects opposite magnetic poles and represents the strength and direction of the magnetic field.
Magnetic Pole
One of the two opposite ends of a magnet
