This video clip refers to the study of the movement of the solid body, which differs from the study of the motion of the material point because in the solid body despite the phenomenon of transportation also exists the effect of rotation. The mass, the conveyor speed, the power, the speed, the energy due to the transport of the material body, correspond to the moment of inertia, the angular rotation velocity, the torque, and the rotational energy of the solid body, respectively. The behavior of the solid body is highlighted through the experiment of rolling a cone in a inclined plane, where the cone instead of descending like when a body slides in an inclined plane because of the friction and the weight, on the contrary rises because of the rotation.
