This document contains notes from a science lesson on acceleration. It defines key terms like motion, velocity, and acceleration and provides examples. Students are instructed to read sections from their textbook, complete practice problems, and work in groups. The teacher discusses demonstrations to illustrate the different terms and includes graphs to analyze speed over time. Warnings are given to students about behavior expectations and homework policies.

1. Mr.Anas Lahrichi

2.  Take 5 min to do the following
 Individual : No discussions
 Open the textbook page 27
 Read the first two paragraphs

3.  WALT : Lesson 3 : Acceleration
 WILF : Focus and participation of everyone
 TIB : Acceleration is mentioned a lot in real
life. For example : there will be acceleration
fines in Paris soon

4.  Target behavior of the month is being
focused
 You need to be following and on-task to get
your merit
 Next office hours are tomorrow after school
 The quizzes/entry tickets will be graded soon
 All these powerpoint slides are on Engrade in
discussions

5.  During a professional drag race, a car can
increase speed and accelerate from 0 to
480km/hr in 5 seconds !
 To slow the car down from such a huge
speed, the driver releases a parachute

6.  Definition of acceleration : change in velocity
during a period of time
 You should know the difference between
Motion, Velocity and Acceleration
 What is motion ?
 Change in position
 What is velocity ?
 Speed + Direction
 What is acceleration ?
 Change in velocity

7.  I will do 3 demonstrations and then you’ll tell
me which term corresponds to each
demonstration
 Which term for demonstration 1 ?
 Motion
 Which term for demonstration 2 ?
 Velocity
 Which term for demonstration 3 ?
 Acceleration

8.  Does direction matter in acceleration ?
 Yes
 If the acceleration is in the same direction as
the motion you speed up
 If the acceleration is in the opposite direction
of motion you slow down
 Check next figure for these cases

10.  Velocity was change of position
 𝑣 =
𝑐ℎ𝑎𝑛𝑔𝑒 𝑖𝑛 𝑑𝑖𝑠𝑡𝑎𝑛𝑐𝑒
𝑐ℎ𝑎𝑛𝑔𝑒 𝑖𝑛 𝑡𝑖𝑚𝑒
 Acceleration is change in velocity
 a=
𝑐ℎ𝑎𝑛𝑔𝑒 𝑖𝑛 𝑠𝑝𝑒𝑒𝑑
𝑐ℎ𝑎𝑛𝑔𝑒 𝑖𝑛 𝑡𝑖𝑚𝑒
 An easier way to write it is :
 𝑎 =
𝑣 𝑓−𝑣 𝑖
𝑡

12.  Voice level 1
 Answer in your notebook
 This is graded as participation
 Do the practice of Math skills page 29

13.  As we learned distance time graphs, there is a
new type of graph : Speed time Graphs
 Time is on horizontal axis
 Speed is on vertical axis

14.  Open textbook page 30
 Each group needs to read from 30 to 32
 Write a summary per group

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.
