1. significant figures (p17)
those digits in a measurement that are known with certainty plus the first digit that is uncertain
2. displacement (p41)
the change in position of an object
3. average velocity (p43)
the total displacement divided by the time interval during which the displacement occured
4. instantaneous velocity (p46)
the velocity of an object at some instant or at a specific point in the object's path
5. acceleration (p48)
the rate at which velocity changes over time; an object ~ if its speed, direction, or both change
6. Equation to find displacement with constant acceleration (given: initial & final velocity, change in time)
Δx = 1/2 (vi + vf) Δt
7. Equation to find velocity with constant acceleration (given: initial velocity, acceleration, change in time)
vf + vi + a Δt
8. Equation to find displacement with constant velocity (given: initial velocity, acceleration, change in time)
Δx = vi Δt + 1/2 a(Δt)2
