U3 - Magnetic Fields & Gravitational Forces

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
