Andy (same name as my younger brother, God bless him he lives in Florida! Just kidding Damien, Nate, Jim and Randy! :-) ),
Here are the key points:
1. Until something else comes along things keep going as they are.
2. When things do collide the subsequent direction is a summation of the mass and velocity of the objects in question.
3. What goes up must come down!
(Editor's note: gravity is a cool thing too!)
Or, better, for ever action there is a equal and opposite reaction!
(sound like a flame war? :-) )
You catching all this?
OK, that wraps it up for Newton's Laws...want to come back to the campfire?
