Coefficient of Friction Experiment

The video tutorial explains an experiment to determine the coefficient of friction using an inclined plane. It outlines the equipment needed, the working formula, and the step-by-step procedure. The experiment involves adjusting the angle of inclination, measuring the height and base length, and recording observations. The process is repeated with varying weights to calculate the mean coefficient of friction.
