### Chapter 9, “Derivative Approach to Motion in One Dimension”

#### Average Velocity

equals the slope between two points on position v. Time graph for any time interval a ≤ t ≤ b.

#### Instantaneous Velocity

at t = a for any function f(t) that gives position as a function of time.

#### Instantaneous Velocity

v = f'(t)

for any position equation that's a function of time, f(t).

#### Average Acceleration

equals the slope between two points on velocity v. Time graph for any ...
