In this lesson we should learn:

about the bodies in space that make up the Universe

why planets and moons stay in orbits

about the planets in our Solar System, producing a model of the Solar System

Foundation Paper

You should now be able to

Know that: Earth is one of a number of planets that orbit the Sun: the Moon orbits Earth; Earth orbits the Sun and the relative positions of Earth, Sun and planets

Know that the Universe consists of: stars and planets, comets and meteors, black holes, large groups of stars called galaxies

Describe why stars can be seen even though they are far away

Describe that gravitational force determines the motion of planets and satellites

Higher paper

Know the relative positions of planets, stars, comets, meteors, galaxies and black holes

Know that circular motion requires a centripetal force and that gravity provides the centripetal force for orbital motion

3 Types of Galaxies

3 Types of Galaxies

Х Elliptical Ц oval shaped, no arms, little gas or dust clouds

Х Spiral Ц bulging nucleus (the center) with a least two arms that contain great clouds of gas & dust coming out on opposite sides (3/4 of all)

Х Irregular Ц stars spread unevenly, no distinct shape, least common

The gravity on neutron stars, white dwarfs and black dwarfs is so strong that it crushes atoms, so the matter in stars is millions of times denser than anything on earth.
