A standard problem for physics students is to calculate or measure the acceleration of an object down an inclined plane. Additional information can be obtained by measuring the angular acceleration as well as the linear acceleration. An experiment is described where a billiard ball was filmed as it rolled down an inclined plane at different inclination angles. The transition from rolling without slipping to rolling with slipping was identified, and the relevant friction coefficients were measured independently from the linear and angular accelerations.

球在倾斜平面上的加速

物理专业学生的一个标准问题是计算或测量物体沿倾斜平面的加速度。通过测量角加速度和线性加速度可以获得其他信息。描述了一个实验，在该实验中，台球以不同的倾斜角度从倾斜平面上滚下来时被拍摄下来。确定了从无滑行滚动到有滑行滚动的过渡，并且独立于线性和角加速度测量了相关的摩擦系数。
