VOCAB:

Orbit- The path of an object as it revolves around another object in space.

Force- A push or pull exerted on an object.

Gravity- The force that pulls objects toward each other.

Universal Law of Gravitation- The scientific law that states that every object in the universe attracts every other object.

One Astronomical Unit = Earth’s average distance from the sun

Mass - A measure of how much matter is in an object

Weight - A measure of the force of gravity on an object

Inertia - The tendency of an object to resist any change in motion (something moving stays moving and something stopped stays stopped)

Nebula- huge cloud of dust and gas with immense volume in space

Protostar- As the gas and dust pull together and compact, it starts to heat up (nuclear fusion). That mass forms the early stages of a star.

Planetesimals -Small asteroid-like and comet-like bodies formed by collision of particles from the solar nebula
