Structure of the Universe
Gravity and the Solar System
What makes up the universe?
How are distances in the universe measured?
What is the structure of the universe?
Earth
The Solar System
Stars
Galaxies
Light-year
9.5 trillion km per year
300,000 km per second
The distance light travels in a year
Clusters and Superclusters

What is Gravity?
What are Kepler's laws?
What is the law of universal gravitation?
How did the solar system form?
A force of attraction between objects that is due to their masses and the distances between them.
Kepler's First Law
Kepler's Second Law
Kepler's Third Law
Each planet orbits the sun in an ellipse with the sun at one focus.
As a planet moves around it's orbit, it sweeps out equal areas at equal times.
The square of the orbital period is proportional to the cube of the planet's average distance from the sun.
p^2=a^3
All objects in the universe attract each other through gravitational force.
How does gravity affect planetary motion?
Centripital force
The inward force that causes an object to move in a circular path
Solar Nebula
A cloud of dust and gas in space
A protostellar disk formed from the collapsed solar nebula
Collapses due to unknown cause
The sun formed at the center of the protostellar disk
Planetesimals formed in the protoplanetary disk
Large bodies of dust from which planets formed
Planets form from planetesimals
