Teach Engineering: Discovering Friction
With a simple demonstration activity, students are introduced to the concept of friction as a force that impedes motion when two surfaces are in contact. Then, in the Associated Activity (Sliding and Stuttering), they work in teams to...

Teach Engineering: Factors Affecting Friction
In this instructional activity, students use previous knowledge about friction to formulate hypotheses concerning the effects of weight and contact area on the amount of friction between two surfaces. In the Associated Activities (Does...

Teach Engineering: Does Weight Matter?
Using the same method for measuring friction that was used in the previous lesson (Discovering Friction), students design and conduct an experiment to determine if weight added incrementally to an object affects the amount of friction...

The Physics Classroom: Energy Conservation on an Incline
This site is a discussion and animation about whether the total mechanical energy of a cart rolling down an incline is conserved, which can be determined if there are any external forces acting upon it.
