Friction in Action
There's no need to have friction among instructors regarding the resource. Pupils investigate how marbles and coins slide along different surfaces which gives them information to estimate coefficients of friction.

Sliders - Static and Kinetic Friction
Learners work in groups to conduct experiments the demonstrate the differences between static and kinetic friction. They consider how friction affects us in our everyday lives, determine the effects of weight on friction and complete a...

TE Lesson: Factors Affecting Friction
Students investigate the effect of weight on normal friction or the friction due to surface roughness. They tell about the effects of contact area that occurs as a result of molecular attraction by looking at data on line graphs.

Introduction to Friction
Students study the properties of the frictional force between two surfaces in contact. They inspect various phenomena in nature where friction plays an important role and demonstrate

What a Drag
Learners learn examples of friction and drag, and suggest ways to reduce the impact of these forces. The equation that governs common frictional forces is introduced, and during a hands-on activity, students experimentally measure a...
