• Setting up lab notebook
• On the first page stick/glue your table of
contents
• On the inside front cover glue the Physics
lab report grading/marking form.
• If you do not have a notebook in the green
bin at the end of today you will receive a
zero grade. (Tomorrow is late!!)
Lesson Objectives
• We will analyze a persons motion to
describe their distance, displacement, and
speed.
• I will design and conduct a lab experiment
to analyze a persons motion in terms of
their displacement, distance, and speed.
Designing a Lab
• Question:
How can I analyze a persons motion at
specific positions and over time?
• Purpose:
To analyze the motion of a running person
at multiple positions for a given time..

Questions
• What data/measurements do we need to
collect?
• What controls do we need to put in place?
• What materials do we need?
• What will your data table look like?
Data collection
• Construct a data table that includes all the
information that must be collected.
• Together with your group conduct the experiment
to gather your data using the hallways to the left
and right of the room as well as the middle
hallway.
• FYI: Misconduct or misbehavior will result in
you sitting out this activity. Remain with your
group. NO wandering.

• Explain what is happening for each line graph on the
distance( position)- time graph shown below. Use
vocabulary such as: constant positive velocity, constant
negative velocity, at rest. Also how does A & B differ?
Challenge: what
would the graph
look like if the
object is speeding
up/accelerating?

Lesson Objectives
• Part1:We will distinguish between vector
and scalar quantities.
• Part2:We will also distinguish between
and calculate average & instantaneous
speed & velocity
• I will create graphic organizers to
distinguish between vectors & scalars,&
average vs instantaneous speed. I will
calculate speed.

Venn Diagram
• In the Venn diagram, Compare &
contrast speed vs. velocity & distance
vs. displacement.
• Then cut & paste or whole punch and
into your notebook/notes.
• Hint: How are they alike, How are they different?
Distance and Displacement
Starting from origin, O a person walks 90-m east, then turns
around and walks 40-m west.
Q: What is the total walked distance?
Q: What is the displacement?
Distance and Displacement
Starting from origin, O a person walks 90-m east, then turns
around and walks 40-m west.
Q: What is the total walked distance? A: 130-m
Q: What is the displacement? A: 50-m, due east.
Speed vs. velocity
How does speed differ from velocity?
Speed
Speed- the distance
travelled in a given
time.
Velocity = Speed with Direction
Velocity can be changed by
changing speed or direction
or both.
Learning check
• Which of these are speed and which
are velocity?
•
•
•
•
40 m/s
60mPH west
50 kPH
30ms-1 northeast
Create a T chart
• Instantaneous velocity
Definition:
Formula:
Units:
Picture:
Average velocity
Average Speed
Average speed equals the total distance traveled
divided by the total time of travel.
Units: m/s or ms-1
(Sometimes-MPH,
kmPH)
Instantaneous speed

mmedia/kinema/trip.cfm
The (velocity) speed at
a given instant in time.
Units: m/s
v=d
t
Velocity = distance
time
Objective
• We will “distinguish” between vector and
scalar quantities.
Differentiate
Compare & contrast
Create a T chart
• Scalars
• Definitions:
• Examples:
Vectors
Vectors and Scalars
physical quantities are divided into scalars and
vectors.
A scalar quantity is one that has only size or
magnitude.
A vector quantity has both magnitude and
direction.
Learning check
• Decide whether these
are scalar or vector
quantities.

Example Problem
• A object at rest travels a distance of 40
