1.0       Introduction

a. define the terms: mechanics, kinematics, dynamics;

1.1       Speed

a.  define the terms: speed and average speed;

b.  given one of speed, distance and time calculate the third;

1.2       Changing Units

a.  use dimensional analysis to convert from one unit to another;

1.3       Reference Frames

a.  describe the motion of an object relative to a particular frame of reference;

1.4       Average Velocity and Displacement

a.  define the terms: velocity, average velocity and displacement;

b.  state the symbols for the above quantities;

c.  given one of average velocity, displacement and time calculate the third;

1.5       Instantaneous Velocity

a.  define instantaneous velocity and show the symbol used to represent it;

b.  compare instantaneous velocity and instantaneous speed;

1.6       Vectors and Scalars

a.  differentiate between a vector quantity and a scalar quantity and state which quantities used in Kinematics are vectors and which are scalars;

1.7       Acceleration

a.  define the terms acceleration, average acceleration and instantaneous acceleration;

b.  state the symbols for the above quantities;

c.  given one of acceleration, change in velocity and time calculate the third;

1.8       Uniformly Accelerated Motion

a.  define uniform accelerated motion;

b.  write from memory the equations used to describe uniformly accelerated motion;

c.  use the equations for uniformly accelerated motion to solve related problems;

 

Part I – INTRODUCTION - Handing out Materials and Vocabulary Review :

 

Ø      Hand out textbooks, record numbers and go over features of the text with students. Specifically the useful data tables on the back cover and the appendices of note on page 310-314 of GORE

Ø      Hand out and go over Physics 12 Course Outline and the Physics 12 learning outcomes.

Ø      Hand out formula sheets from Provincial Exam Booklet.

Ø      Hand out the vocabulary terms for Unit One and review the terms. Remind students that the fundamental quantities of distance and time are both scalar whereas change in position is a vector. speed = distance / time, velocity = displacement / time, acceleration = change in velocity / time. Consequently, speed is scalar while velocity and acceleration are vectors.
