- Friction prevents the metal washer on incline from slipping. Washer will begin to slide down plane when angle is great enough (one can show that the coefficient of friction is equal to the tangent of the angle when the washer just begins to slip). Materials include: rubber, glass, wood, and teflon.
- Use angle ruler (shown in photo) to measure angle.
- Materials located in L02, section B3. Angle ruler in L45, with rulers.
- Used in uniform circular motion lab, coeficient of static
friction is calculated and then used to predict maximum rpm at which car will
remain on table.
- Adjust rpm with 5 amp, regulated DC power supply.
