1. Motion in One Dimension
Kinematics
(continued)

2. Describing Motion in 1-D
Consider uniform acceleration (a = constant)
Goal is finding equations for:
Velocity as a function of time
Displacement as a function of time
Velocity as a function of displacement
Use definitions for _________ acceleration and _________ velocity

3. Motion in 1-D with Uniform a
Procedure:
______________ manipulate equations
Remove all f subscripts
Change all i subscripts to 0
Let t0 = ____
First: derive expression v as function of t
___________________________________________

4. Evaluate Velocity for Uniform a
Velocity is ________ function of time (v = v0 + at)
Average velocity is _________ between v and v0
Equation [2.7]

5. Summary of Motion in 1-D with Constant a
When a = 0 these equations correspond to _________ motion (v = constant)

6. Freely Falling Objects
The only acceleration is due to _________
There is no air __________ to impede the motion
Gravity provides a constant (uniform) acceleration _____________________________
Replace x with y to indicate vertical position in equations of motion
