Rolling 滚动 , Torque and Angular momentum 下载积分: 3000 内容提示: Rolling 滾動 , Torque and Angular momentum• Rolling is a combination of translation of the center and rotation about the center. Since the rolling distance is:The speed of center of mass is: 文档格式:PPT | 页数:21 |...
There is also a close relationship between torque and angular momentum: T net = dl/dt The vector sums of all the torques acting on a particle is equal to the time rate of change in the angular momentum of that particle. The torques and angular momentum are both defined wrt the same ...

Eventually, the disk begins to roll without slipping on the surface, and the question asks for its final angular speed. Equations for torque, angular acceleration, and angular velocity are used, but equations for translation and conservation of angular momentum could also be used to find the ...
These papers addressed the common misconception that the instantaneous point of contact of the rolling body with the plane can be used to evaluate the angular momentum L and the torque τ in the equation of motion dL/dt =τ. To obtain the correct equation of motion, the 'phantom torque' ...
It is a widespread misunderstanding in introductory physics courses that the motion of rolling bodies in general can be calculated using the point of contact as a reference point when equating the rate of change of angular momentum to the torque. In this paper I discuss in general two correct ...
