Sliding Mass Problems
Physics masters solve five sliding mass problems. For each, there are a few different values to be determined: normal force, force of friction, acceleration, velocity, coefficient of friction, or net force. Pupils must draw a force...

Friction
Students explore the force of friction between materials. In this physics lesson, students participate in an experiment using various materials such as wood, waxed paper, and aluminum foil and explore which item produced the most friction.

Teach Engineering: Imagine Life Without Friction
Students are introduced to the concept of inertia and its application to a world without the force of friction acting on moving objects. When an object is in motion, friction tends to be the force that acts on this object to slow it down...

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.
