Overall Expectations


Demonstrate an understanding of the
relationship between
forces

and the
acceleration of an object in linear motion



Investigate, through experimentation, the
effect of a net force on
the linear motion of an object
, and analyse the effect in
quantitative terms, using graphs, free
-
body diagrams, and vector
diagrams



Describe the
contributions of Galileo and Newton

to the
understanding of dynamics; evaluate and describe
technological
advances

related to motion; and identify the effects of societal
influences on
transportation and safety issues


(Ontario Ministry of Education, 2000)

Building an Accelerometer


Step 1:
Cut out the accelerometer guide provided by your
teacher and glue to an index card. Be sure to align the top edge
of the guide with the top of the card.


Step 2
: Use a piece of tape to attach a piece of string to the top
of the index card at the center point of the guide. Tie a washer to
the bottom of the string.


Step 3:
Center the index card on a ruler and tape it to the ruler.


Step 4
: Hold the bottom end of the ruler as you walk. Try to keep
the accelerometer steady as you walk. What do you observe?

Culminating Activity


Part A: Research (K/U)


Research the motion of a car: the forces involved, factors
affecting stability, vulnerabilities



Part B: Investigate and Analyze (I; A)


Road test with accelerometer


Develop recommendations to improve safety



Part C: Communicate (C)


Present findings and recommendations to class

Summary


Students should leave the course understanding:


that forces occur everywhere in nature and are required for
our daily living



the ways in which forces and the acceleration of an object
are related by Newton’s three laws of motion




Our goal: relate classroom learning to the real world
and students’ own daily lives



This the foundation of the course and future physics
courses


Take your time and
HAVE FUN!
