This document contains notes from a science class. It outlines topics to be covered, including definitions of velocity and acceleration, as well as a review of concepts from Lessons 1 and 2 in preparation for an exam. Students are reminded of homework due dates and warned that missing assignments will affect their grades. The notes also provide examples of speed and velocity calculations and contain a student warning list.

1. Mr.Anas Lahrichi

2.  Listen carefully to the instructions
 15 min
 Individual/no discussions
 Raise your hand quietly for questions and
wait for me to come
 You cannot switch once you have chosen a
quiz

4.  Review Session today
 Exam on Lesson 1 and Lesson 2 Thursday
27th September => Review book from NOS4
to NOS18 + worksheets and homework +
previous quizzes
 Start thinking about your science fair project

5.  WALT : Definition of velocity
 Changes in velocity
 Acceleration introduction
 Review session
 WILF : You need to be up to date with your
materials and have clarifying questions ready
 TIB : The direction in which the object is moving
is important to factor in. There is a difference
betzeen driving to a wall and driving on the road

6.  The acceleration of a model rocket could
reach 90
𝑚
𝑠2 = 90
𝑚
𝑠
𝑠
 That is 324km/hr more every second

7.  Lesson 1 Review page 24
 Due : Thursday 27th September
 Hardcopy of Lesson 1 review will be handed
out

8.  Speed is distance over time (average and
instantaneous)
 Motion could be graphed on distance-time graphs
 Distance time graphs show how distance (dependent
variable) varies over time (independent variable)
 The steeper the graph the faster the object
 Speed could be calculated from the graph
 More than one object’s motion could be put inn one
graph

9. Straight line : constant
speed
Curved line : changing
speed

10. • Answer : Yes in the
direction of motion
• Velocity = Speed +
Direction
• Based on a reference
direction,one speed will be
positive and the other
negative (see figure)

11.  Since we have the direction added, arrows are
a great tool
 The length of the arrow represents how fast
the object is moving
 In Math, we call these vectors

16. • We open the book at lesson 1 and we go through the
concepts together
• Each student will answer a question asked by me
• When you go home make summaries and memorize the
formulas (you will ned calculators)

18.  Do not talk unless you have
permission (Raise your hand)
 No talking back (Come see in end
of class)
 Stay focused and on task
 Respect your classmates and
teacher
 Be prepared

19.  You are expected to do your homework on the
due date (no excuses)
 Every time you miss a homework you get a
strike,after 3 your parents are informed
 Not doing your homework will negatively affect
your grade in participation and quizzes

20.  The corrected quiz as well as rubrics will be
posted on Engrade.
 An individual assesment means no discussion at
all. Any talking will result in a 0.
 Come see me right after class or office hours to
discuss your copy, do not bring it up inside class.
 Any copy written in pencil cannot be considered
for re-grading, use a pen.
