Test: Chapters 2 and 3 in Text Book
YOU ARE RESPONSIBLE FOR EVERYTHING IN THIS CHAPTER EVEN IF IT IS NOT COVERED ON THE REVIEW!!!
BEST HINT: USE YOUR QUIZ/HW PROBES/ICAS TO REVIEW!!!
Topics:
1. Basic Skills: Significant Figures, Unit Conversion, Scientific Notation – Pg 940 – 941
Identifying sig figs Operations involving sig figs
Unit Conversion method/dimensional analysis
Converting into and out of scientific notation Operations involving sci notation
2. Drawing and Interpreting Graphs – Pg 943 – pg 944
(Displacement – time)(Velocity – time)( Accelerations – time)
Create one from the other
Slopes, tangents, areas under curve
3. Velocity, Average velocity, displacement, speed, distance: Uniform motion
Displacement and velocity – Page 34-45
Constant, Average, and Instantaneous Velocity – Page 47-57
4. Kinematic Equations: (worked out example questions) – Pg 84-89: Accelerated Motion
One step problems including quadratic equation
Gravity questions Multi-step problems (challenges)
5. Relative Velocity (pages 104-110)
6. Vector Analysis (pages 90-103 but you really need to only do vectors mathematically not graphically)
Definitions: For each definition, you should be able to define what it is, how to find it on different graphs or an example of it. You may use diagrams to help as well. You should also be able to tell the difference between terms like distance and displacement.
Velocity vs. Speed Distance vs. Displacement Vector vs. Scalar
Negative acceleration vs. positive acceleration (different cases)
Gravity instantaneous velocity vs. average velocity
Average acceleration vs. instantaneous acceleration
Uniform motion vs. non-uniform motion
NOTE: All answers are found in the back of your text book.

From Worksheets: Look at the v-t graphs and d-t graphs sheets including questions from textbook
Some Extras:
1) Draw v-t and a-t graphs for the following d-t graph:
2) Reading v-t graphs:
a) velocity (0)
b) velocity (5.5)
c) When is the object going forward?
d) When is the object stopped?
e) a (3)
f) a (5)
g) When is the object going -1 m/s?
h) How far did the object go in the first 5 seconds?
i) Displacement for first 5 seconds
j) Displacement for entire trip?
k) Speed over entire trip?
3) word problems: A) The distance from Halifax to New York is 2546 km. If it took you 18.6 hours to drive there, what would your average speed for the entire journey be? Did you obey the speed limits assuming you drove on a typical highway?
B) Mrs. Evans travels 70 km/h [E] for the first 15 minutes and then travels 50 km/h [W] for the last 5 minutes on her way to school.
a) Find her displacement over the 2 parts of the trip.
b) What is her instantaneous speed at 10 min?
c) What is her average velocity over the entire trip? Average speed?
4) A car accelerates from rest to a velocity of +80.0 km/h in 6.3 s. What was the average acceleration? What does this type of acceleration mean?
Vectors
For each question, draw a vector diagram. Include sig. figs and units/directions in your answer.
Use the following vectors:
1. (1.5) 2 ½ (1.5)
3. (3) 4. (3)
5. -2() (2)
6. On the walkathon, Mr. Hammer rode a bicycle. He drove 2km [E] then 15km[N]. Then he went 11km[S]. Finally he left the trail (unbeknownst to Mr. Savage!) and went 5 km [W].
a) What is his final displacement? (3)
b) If it takes Mr. Hammer 30 minutes, what is his velocity? (1)
c) What is his speed? (2)
