Tire Materials and How They Affect Friction: From Atoms to Surface Dynamics

Friction is a resistive force between two surfaces that slide against each other. This experiment investigated how different materials affect frictional behavior on an imitation road surface. Rubber, ABS plastic, aluminum, and poplar were all dry-slid using a paver stone as a ramp to imitate asphalt. Each material was placed on top of the ramp. Then, the angle was increased until the sample moved. Additionally, the angle for the object to fall at a constant velocity was found. Each material was
