Assignments

Match Graph Lab Questions due Monday 9/13
Ch. 2 Section 2 Review Questions 5 & 6(p. 59)  due Friday 9/17
Practice 2B problems  (p. 49) due Friday 9/17

Important Vocabulary:

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

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)
