What are Newton's Laws of motion?
Intertia
F = ma
Action/Reaction pairs

What are the four characteristics of waves? Define each.
Reflection (bounce off)
Refraction (Looks like it bends through different mediums)
Defraction (bends around)
Interference (Two waves interact with each other)

What is the order of energy? Which is most efficient?
KE/GPE --> EP --> NP --> EP --> CP --> Thermal. Thermal.

What are the evidences of the big bang?
Cosmological Red shift
Expansion of universe
H/He Ratio

What is the nebular hypothesis?
Dust and whatnot gets attracted together, and comes together via gravity. This creates planets. They start to move and spin (angular momentum), which make all the planets on the same plane. Jovian planets are large because they take up very available resources, while terrestrial planets are small because they use not-readily-available resources.

Explain the motion of gravity and acceleration when a ball is thrown up in the air.
Gravity is always in motion. Acceleration is always occuring. Acceleration increases when you toss it up, though it decreases towards the top. Acceleration hits 0 at the top, then increases as gravity pulls it back down.
Extra: GPE increases as it goes up. Kinetic energy decreases as it goes to the top and increases as it falls
