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)

Unit Structure Displacement, Velocity, Acceleration Acceleration and the Force of Gravity Newton’s Laws of Motion Overarching theme: vehicle design and safety

Displacement, Velocity and Acceleration

Key Topics Scalars and Vectors Distance and Displacement Speed and Velocity Position-time Graphs Uniform Acceleration Velocity-time Graphs Equations for Uniformly accelerated Motion

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?

Accommodations Modified handouts  E.g. more graphics rather than text Assistance with computer technology Creating groups which assist students with difficulties

Assessment Strategies Diagnostic:  Think/Pair/Share, pre-quizzes, homework checks Formative:  Worksheets, investigations, labs Summative:  Culminating activity Learning skills also assessed throughout

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

Culminating Activity Evaluation: 1. Teacher self-evaluation 2. Group evaluation of individual members 3. Peer evaluation of presentations 4. Learning skills assessed through teacher-student conferencing over duration of project

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!
