SPECIFIC EXPECTATIONS
By the end of this course, students will:
B1.1 analyse, on the basis of research, a technology that applies concepts related to kinematics (e.g., devices used to measure speed in sports; rocket accelerators; motion-detecting sensors for security systems; speedometers in automobiles) [IP, PR, AI, C]
Sample questions: How does a speed gun measure the motion of a ball thrown by a baseball pitcher? How are accelerometers used to study the motion of animals in wilderness settings? How are accelerometers used in video game consoles? What type of device is used to monitor false starts in a sprint? How does
it work?
B1.2 assess the impact on society and the environ- ment of a technology that applies concepts related to kinematics (e.g., photo radar helps prevent vehicular accidents and reduces fuel consumption associated with excessive speeding) [AI, C]
Sample issue: The use of the global positioning system (GPS) increases accuracy in mapping, surveying, navigation, monitoring earthquakes, and tracking the movement of oil spills and forest fires, among other benefits. However, its extensive use raises concerns about privacy and human rights.
Sample questions: How are satellites used to track animal species in remote areas? How can scientists and environmentalists use this infor- mation to help protect vulnerable species? What is the impact of the use of speed limiters and tracking devices in the trucking industry? What effect do lower truck speeds have on highway safety and vehicle emissions?
By the end of this course, students will:
B2.1 use appropriate terminology related to kinematics, including, but not limited to: time, distance, position, displacement, speed, velocity, and acceleration [C]
B2.2 analyse and interpret position–time, velocity– time, and acceleration–time graphs of motion in one dimension (e.g., use tangent slopes to create velocity–time graphs from position–time graphs and acceleration–time graphs from velocity–time graphs; use the area under the curve to create position–time graphs from velocity–time graphs and velocity–time graphs from acceleration–time graphs) [AI, C]
B2.3 use a velocity–time graph for constant accel- eration to derive the equation for average velocity [e.g., vav = (v1 + v2)/2] and the equations for displacement [e.g., Δd = ((v1 + v2 )/2) Δt,
Δd = v1Δt + 1⁄2 a (Δt2)], and solve simple problems in one dimension using these equations [AI]
