For this experiment, you have to find the inclined angle (θ) for which the motion of the object placed over the inclined is impending.

Find the average coefficient of friction (static) for each of the case highlighted below.
For each case, perform the experiment at least five times. Since, the random error has been modelled into the system, you will get different reading each time.
For performing the experiment, select the material of the inclined plane and the mass, refresh the page, and move the slider below to change the inclination angle.
Before taking the reading, please refresh the page.
At the instances, when the motion of the block is impending, the block color will change from green to red.
