Demo Title: Static Friction - Rolling Wheel
Condition: Good
Principle: Surface Friction of Rolling Wheels
Area of Study: Mechanics
Equipment:
Bicycle Wheel, Lawnmower Wheel on Axel
Procedure:
Roll the wheel along the top of the lecture bench. Discussions of zero velocity at the point of contact and friction of rolling objects can be illustrated.
