Lesson 3: Friction
Duration of Days: 6
Lesson Objective
Students will make the distinction between static and kinetic friction. They will also apply this to static and dynamic equilibrium when solving problems for forces being applied to an object. Students will also determine the coefficient of friction for a wooden block and metallic ramp using data collected during a lab procedure.

GS2: Investigation
Students can design and conduct appropriate scientific investigations.
GS4: Data Analysis and Interpretation
Students can analyze and interpret scientific data and solve problems using a range of tools, technology and mathematical techniques.
This lesson will introduce students to friction, its formula and how the materials involved affect the force through its coefficient of friction. This applies to a opposing force to others later in the unit.
