Coulomb’s Law
A torsion balance is used in a quantitative analysis of the relationship among charge, distance and electrostatic force to verify Coulomb’s law. Compares Coulomb’s law of electrostatic force and Newton’s law of universal gravitational force.

Work and Energy
Elevators, escalators and an amusement park ride explain mechanical energy transformations and provide data to calculate the work done and power developed. Examines the principles of work, power and energy, and analyses data obtained from an air table.
-
Energy Conservation
Analyses the transformation of gravitational potential energy to kinetic energy using algebraic and graphical means. The motion of a mass on a spring and a bungy jump provides the data for analyses that support the principle of energy conservation.
-
Energy Transformation
The work-energy theorem is used to solve problems involving change of gravitational potential energy to mechanical kinetic energy and the work done against friction. Roller coasters and water slides provide examples for algebraic and graphical analysis.
-
Momentum and Impulse
Information is gathered from a vehicle-safety expert and a self-defence instructor and used in an exploration of the concepts of momentum and impulse. Teacher-guided analyses relate additional demonstrations of the principles of momentum and impulse.
