5. Concept of Friction Force
Session 2: How can we change the friction force – Step 1 Challenge and conception of the experiments
Objective 1: To experiments how to change a friction force.
Objective 2: To develop with the student an experiment in order to compare several test of friction forces, and the effect of changing parameters.
Session 3: How can we change the friction force – Step 2 Scientific approach
Objective : Experiments with a scientific approach to the modification of area resisting motion.
