Important Vocabulary:

bulletacceleration
bulletpositive acceleration
bulletnegative acceleration
bulletdeceleration (not the same as negative acceleration)
bulletfreefall

Watch out for misconceptions!

bulletnegative acceleration does not always mean an object is slowing down
(see table 2-3 on p. 51)
bulletAcceleration is a vector, and must have a direction.
bulletNegative signs denote direction.  Negative velocity means velocity in the negative direction.  Negative acceleration means acceleration in the negative direction.

Important Equations:

a = Δv/Δt

vave = 1/2 (vi + vf)
