1. Be sure your lab pages are numbered (7-7c).
Add one more (7d) to glue in your lab analysis questions from Friday.
Set up the NEXT page as follows:
page = 8
date =
title = Kinematics Notes
Set up your page for Cornell notes
essential question = How can I describe the concepts of one-dimensional motion?

2. How Far? SI units = meters (m)
POSITION: where an object is located relative to an origin
DISTANCE: total length of travel
scalar quantity (has no particular direction)
DISPLACEMENT: change in position, or how far away an object is from its starting point
vector quantity (has a specific direction)

3. practice 4.3 mi + 4.3 mi = 8.6 mi 4.3 mi + 4.3 mi + 2.1 mi = 10.7 mi
Before describing motion, you must set up a coordinate system by defining an origin and a positive direction.
If you drive from your house to the grocery store and back, what is the total distance you traveled?
4.3 mi mi = 8.6 mi
If you drive from your house to the grocery store and then to your friend’s house, what is your total distance? What is your displacement?
4.3 mi mi mi = 10.7 mi
2.1 mi

4. HOW FAST? SI units = meters per second (m/s)
SPEED: how fast an object is moving
average speed = distance traveled / time elapsed
scalar quantity
ALWAYS positive
VELOCITY: how fast an object is moving in a particular direction
average velocity = displacement / time elapsed
vector quantity
can be positive or negative

5. practice What is his overall average speed?
A runner sprints 50.0 m in 8.0 s.
What is his average sprinting velocity?
He walks back to the start in 40.0 s.
What is his average walking velocity?
displacement / time = 50.0 m / 8.0 s = 6.3 m/s
displacement / time = 50.0 m / 40.0 s = 1.25 m/s
What is his overall average speed?
What is his overall average velocity?
distance / time = m / 48.0 s = 2.08 m/s
ZERO / 48.0 s = ZERO

6. acceleration ∆v ∆t = vf −vi t ACCELERATION: a change in velocity
SI units = meters per second per second (m/s2)
average acceleration = change in velocity / time it took to change
∆v ∆t = vf −vi t
vector quantity
can be positive or negative

7. -1.8 m/s2 practice change in velocity time elapsed
A runner traveling at 3.0 m/s sees the finish line ahead and begins to slow down, coming to a complete stop in 1.7 seconds. What is his average acceleration?
change in velocity
time elapsed
0 m s −3.0 m/s 1.7 s
−3.0 m/s 1.7 s = = =
-1.8 m/s2
