Sliders - Static and Kinetic Friction

Students design a roller coaster and demonstrate their knowledge of Potential and Kinetic Energy. They determine the average velocity a given marble travels on their roller coaster and apply their knowledge of various measurement systems...

Students experiment with potential and kinetic energy. They design a device that will toss a ball at least 30 centimeters, catch it and to the ball up again.

Students apply their knowledge of friction, drag, mass and gravity as they design, build, and test mini-bobsleds.

Students design and conduct experiment to determine if weight added incrementally to an object affects amount of friction encountered when it slides across a flat surface. They graph data from their experiments, and calculate...

Learners watch a demonstration that introduces them to the idea that friction is a force that impedes motion when two surfaces are in contact. They work in groups to experiment with frictional force using a coffee cup on which they alter...

Why do sprinters wear spiked shoes? Scholars explore various styles of shoes and how they handle forces when running. Scholars adjust variables including shoe type, horizontal force, surface type, and normal force to determine which...

Students explain the concepts of kinetic and potential energy and how it can change forms.  In this energy, motion, and frictional forces lesson students participate in a hands on activity that includes calculating energy.

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.

Students investigate the friction between tires and the road and how it affects the movement of cars while driving. They discuss and define friction, experiment with sandpaper and wax paper to determine which material provides the least...

Students 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...
